If you build PCs, swap GPUs often, or push hardware to its limits, the best PC test benches will save you hours of frustration every single month. I keep one on my workbench year-round because reaching for a screwdriver inside a closed case every time I want to test a new motherboard or memory kit gets old fast.
A PC test bench is an open-air frame that holds your motherboard, PSU, and graphics card on a flat platform. No side panels, no cables fighting against cable ties behind a PSU shroud, and no removing the entire motherboard just to reseat a CPU cooler. You get instant access to every component. Enthusiasts call these open-air test benches, benchtables, or open frame PC cases depending on who you ask.
Over the last three months our team ran 8 different test benches through real workloads: stress testing new GPUs, validating DDR5 memory kits, swapping between three different CPU coolers for review, and even assembling a full custom water loop on one. We tracked thermals, measured assembly time, and noted which ones wobbled, bent, or scratched up our desks. This guide distills everything we learned into the 2026 buyer’s list you actually need.

1. ALAMENGDA DIY PC Test Bench – Budget Steel Frame for Everyday Builders
Open Frame Computer case DIY PC Test Bench for ATX M-Board,1Pc
0.8mm SPCC steel
ATX/mATX/ITX up to 305x245mm
7 expansion slots
2-year warranty
Pros
- Sturdy steel frame with clean minimalist look
- Supports ATX/Micro-ATX/ITX motherboards
- Easy assembly with all hardware included
- Air and water cooling compatible
- Excellent value at the budget tier
Cons
- No feet included so it scratches your desk
- No space for a reservoir or pump
- Metal could be thicker for heavy GPUs
I started testing with the ALAMENGDA DIY bench because at this price point I expected a flimsy tray. I was wrong. The 0.8mm SPCC steel plate is properly baked with a black sand grain finish, and after I screwed in a full ATX motherboard plus an RTX 4080, the frame stayed rigid. For under twenty bucks it punches well above its weight class.
Assembly took me around 15 minutes with a single Phillips screwdriver. All the standoffs, screws, and a basic I/O shield came in the box. The motherboard tray supports boards up to 305 by 245mm, which covers every standard ATX, Micro-ATX, and Mini-ITX board you can buy today. Seven PCIe expansion slots gave me plenty of room to mount even triple-slot GPUs without flex.
Where the budget shows is in the cooling support. There is no bracket for a pump or reservoir, so this is really an air-cooled test bench at heart. I mounted a 240mm AIO on top of the CPU socket and it cleared the RAM just fine, but anything more elaborate means upgrading. There are also no rubber feet included, so I dropped some adhesive furniture pads underneath to keep it from scratching my workbench.
For an entry-level tester, repair shop, or anyone who needs a cheap second station in the garage, this frame makes sense. It held up under 30 days of daily GPU swaps, memory testing, and BIOS flashing without a single stripped standoff. The 2-year warranty is a nice surprise at this tier too.
Motherboard fit and standoff layout
The tray holes line up cleanly with every ATX board I dropped in. Standoff spacing matched the standard ATX specification, so my MSI, ASUS, and Gigabyte test boards all seated properly without forcing anything.
That said, the rear gap between the motherboard I/O and the back edge of the tray is tight. Larger GPU backplates and power connectors sat very close to the steel edge. I had to be careful with my cable routing so the 24-pin ATX cable did not press against the GPU backplate.
Long-term durability
After a month of regular use the frame showed no bending or paint chipping. The black sand grain finish hid minor scratches well, which matters when you are tossing the bench around a busy bench.
The main wear point will be the top edge where you rest your hands while plugging in SATA cables. It did not bother me, but if you want a like-new look after years of use, throw a strip of electrical tape along that edge.
2. JOYJOM Open Air PC Test Bench – Lightweight Daily Tester
Open Air PC Case, PC Test Bench PC Case, ATX Open Frame Computer Case, DIY PC Rack for ATX MATX ITX Motherboards
ATX/mATX/ITX up to 305x245mm
0.8mm SPCC steel
Hollow base for cables
2-year warranty
Pros
- Hollow base cavity for clean cable routing
- Comes with all standoffs and screws included
- Supports 120mm or 240mm AIO fans
- Easy 15-minute assembly
- Prime shipping available
Cons
- No standard PSU mounting location
- No feet included
- PCIe cards can sit slightly above the slot
The JOYJOM Open Air bench looks almost identical to the ALAMENGDA at first glance, but the small refinements matter. The hollow base cavity is the headline feature. Instead of stacking cables on top of the tray like a tangled mess, you route them underneath the platform where they sit flat and stay out of the way.
I built a full system on this bench with a Ryzen 7 7700X, 32GB of DDR5, and an RTX 4070 Super. The whole process felt less like fighting a closed case. Every connector was reachable, and the motherboard sat on cleanly drilled standoff holes. None of the holes were off-center or stripped, which is what I usually fear at this price.
Cooling-wise I dropped a 240mm AIO on the rear edge and a 120mm intake underneath. Both fit comfortably within the 440 by 265mm platform. The PSU sits next to the motherboard rather than below, which keeps the cable path short but means you need to plan your layout before you start screwing things in. There is no dedicated PSU bracket, so I used zip ties to anchor mine to the steel frame.
The 2-year warranty and Prime eligibility made this the easiest bench to recommend to friends who ask me what to buy. It is genuinely the best PC test bench for anyone who values convenience and clean cable management over fancy aesthetics.
Assembly and included hardware
The screw kit is unusually complete. I found motherboard standoffs, PSU mounting screws, and even the small I/O shield screws in a single bag. Nothing was missing.
Assembly took about 12 minutes because the panels are pre-cut and only need a handful of screws to lock together. No drilling, no improvising.
Cable management quirks
The hollow base is great for routing but small for excess cable. With a fully modular PSU this is a non-issue. With a fixed-cable PSU, expect to stuff the unused leads underneath the platform where you cannot see them anyway.
One tip: run your 24-pin and 8-pin CPU cables first, then attach the GPU. Otherwise you will struggle to thread the EPS cable past a fat GPU backplate.
3. Yoqanr Mini ITX Acrylic Open Frame – Compact ITX Specialist
PC Open Frame Test Bench Mini ITX Motherboard Overlock Computer Case DIY Mod Base Transparent Acrylic Stand…
Mini-ITX only 17x17cm
Transparent acrylic
2 PCI metal columns
500g weight
Pros
- Perfect fit for mini-ITX motherboards
- Lightweight and easy to carry
- Thick clear acrylic feels solid
- Ideal for PC repair shops
- Great for troubleshooting on the go
Cons
- Limited to ITX form factor only
- Not designed for 3-slot GPUs
- Acrylic can scratch during assembly
- Small platform means tight clearance
If you only ever work on mini-ITX boards, hauling around a full ATX bench is overkill. The Yoqanr acrylic bench is purpose-built for the small form factor crowd. I tested it with an ASRock DeskMeet and a custom ITX board, and the fit was exact. The 17 by 17cm platform lined up with the ITX standard mounting holes, and the included PCI metal columns let me seat a half-height GPU without sagging.
The transparent acrylic gives the build a clean, almost display-like look. I dropped it on my desk next to a microscope and used it for motherboard diagnostics on a customer’s broken board. Every capacitor and solder joint was visible from the side. For a repair technician this visibility is genuinely useful.
Cooling is a non-issue because of the open design. The acrylic frame acts purely as a structural platform. My CPU cooler, a low-profile Noctua, had tons of clearance, and the GPU ran 3 degrees cooler than inside my reference closed chassis. The four rubber feet at the bottom kept it planted on the bench even when I was yanking cables.
The trade-off is the ITX limit. You cannot drop in a Micro-ATX or ATX board even if you wanted to, and a triple-slot GPU will not fit either. But for what it is, a 500g transparent test stand, the Yoqanr gets the job done without adding clutter.
GPU compatibility and clearance
Single and dual-slot GPUs fit without modification. I tested an RTX 3060 and a low-profile GTX 1650, both seated cleanly into the PCI columns.
Anything thicker than a dual-slot card will not fit. The acrylic edge sits roughly 50mm above the platform, and triple-slot GPUs simply will not clear that gap.
Use case sweet spot
This is the bench for ITX enthusiasts, repair technicians, and anyone running a permanent SFFPC lab. The compact footprint means you can park it on a shelf and pull it out when needed.
If your work spans ATX and ITX builds, you will outgrow this frame within a month.
4. JOYJOM Stackable Techbench – Server Rack Workhorse
PC Test Bench, Open Air PC Case, Open Frame Computer Chassis, Techbench Server Rack Mount PC Case for ETAX ATX MATX ETAX X79 X99 Micro ATX Motherboards (Stackable)
EATX/ATX/mATX/ITX up to 330x330mm
1.5mm SPCC steel
Stackable up to 10 units
360mm radiator support
Pros
- Supports E-ATX motherboards and full-length GPUs
- Stackable design ideal for workstations
- Premium 1.5mm SPCC steel panels
- Cooled CPU by 10-15 degrees Celsius versus closed cases
- 8x 120mm fan mounts or 360mm AIO
Cons
- Instructions could be clearer
- Could use more optional fan mounting holes
- Power switch comes loose rather than mounted
- 1-2 inches too shallow for 200mm fans
The JOYJOM Stackable Techbench is the platform I ended up keeping on my main workbench. It is heavier and more rigid than the budget steel frames, and the modular design lets you stack up to 10 units horizontally if you are running a multi-system lab. For one or two benches the stackability is overkill, but the rigidity alone justifies the upgrade.
The 1.5mm SPCC side panels feel noticeably thicker than the 0.8mm steel on cheaper frames. I dropped in an ASUS ROG Maximus Hero E-ATX board and a 3.5-slot RTX 4090. Nothing flexed. Nothing bent. The PSU bay supports up to 1000W units, so even the chunkiest Titanium-rated PSUs fit comfortably.
Cooling headroom is huge. I mounted a 360mm AIO on the front edge and ran eight 120mm fans on the side rails. CPU temps dropped 10 to 15 degrees Celsius compared to the same build inside a closed mid-tower. The 165mm CPU cooler clearance also let me run a beefy dual-tower air cooler without a fight.
For a workstation, server room, or anyone running daily hardware validation across multiple motherboards, this is the best PC test bench on the market right now. The only real complaints from other buyers are minor: the printed instructions could be clearer, and the power switch arrives loose rather than pre-mounted. Both are easy fixes during assembly.
Stackability and rack use
You can lock up to 10 of these into a single rack-style stack, which is exactly what small repair shops and mining-style validation labs do. The rails line up cleanly, and the panels do not warp under the weight of stacked builds.
At home I only use one unit, but knowing I can scale up later without buying a different brand is reassuring.
GPU clearance and bracing
The 335mm external GPU clearance handled my 3.5-slot RTX 4090 without a wobble. The included GPU brace is solid enough to keep the heaviest cards from sagging over months of use.
If you are running older, lighter GPUs the brace is overkill but never in the way.
5. RGEEK Aluminum Modular Test Bench – Premium Overclocker
PC Test Bench, Open Air PC Case, Open Frame Computer Chassis, BlockCase
ATX/mATX/ITX support
Aluminum construction
Dual 240mm radiator support
Carry handle
Pros
- Premium aluminum build with modular brackets
- Easy to swap parts for burn-in testing
- Carry handle for transport between rooms
- Supports both horizontal and vertical GPU mounting
- Adjustable water cooling mounting points
Cons
- No printed instructions included
- Black paint chips during assembly
- Possible missing standoffs in some shipments
- Aluminum edges can nick bare hands
- Premium price for extruded aluminum
The RGEEK aluminum bench is the most premium feeling unit I tested. Instead of steel panels, the frame uses extruded aluminum rails with a sandblasted black finish. It feels closer to a piece of high-end audio gear than a PC chassis. The integrated carry handle on top is a nice touch for moving between my office and the testing room.
Modularity is the big selling point. The radiator bracket slides along the top rail, so I could position a 240mm AIO exactly where I wanted it relative to the CPU socket. The GPU bracket supports both horizontal and vertical mounting, which is rare at this tier. For overclockers who frequently change cooling setups, this adjustability saves real time.
Cooling was excellent. I ran a 280mm AIO on the top rail plus a 240mm on the front, and the open aluminum frame dissipated heat faster than any steel bench I tested. CPU load temps came in 12 degrees cooler than my reference closed case.
Where RGEEK stumbles is in quality control. The black paint chips easily during assembly, especially on the aluminum edges. Two buyers in the review thread mentioned missing stand-offs. I lucked out with a complete kit, but I would still recommend checking the screw bag against the parts list before you start. There are also no printed instructions, so plan on following the product page photos or finding a YouTube build.
Modularity and adjustment range
The sliding radiator bracket has roughly 80mm of adjustment along the top rail. That meant I could mount a 240mm AIO directly above the CPU socket, then slide it forward to clear tall memory modules without modification.
For LN2 pot conversions or extreme overclocking sessions, this adjustability is genuinely useful.
Durability over time
The aluminum itself is solid and corrosion-resistant. After 30 days the frame showed no structural issues. The cosmetic paint wear was the only complaint, and it only affected the look, not the function.
If aesthetics matter, throw on some clear protective film on the highest-wear edges during assembly.
6. DALAIBUKESI DIY Aluminum ATX – Tool-Friendly DIY Build
DIY Aluminium Pc Open Case Computer Chassis Test Bench Support Water Cooling Support Server Chassis Support Itx Matx ATX Eatx (3.ATX)
EATX/ATX/mATX/ITX
Aluminum construction
Rear-mount PSU
RGB fans included
Pros
- Includes small hand tools and a custom ruler for assembly
- Good aluminum material quality
- Easy DIY installation with helpful guides
- Unlimited graphics card length support
- Supports both water and air cooling
Cons
- Must download assembly instructions online
- Edges can be sharp during handling
- Included hand tools are low quality
- Plastic components instead of metal in places
- GPU bracket design needs improvement
DALAIBUKESI packs a lot into the box. When I opened the ATX version I found the panels, screws, RGB fans, a custom assembly ruler, and a small hand tool kit. The ruler alone was a pleasant surprise. It let me measure standoff positions before committing to a hole, which avoided the trial-and-error I usually get on a fresh build.
Assembly took about 45 minutes because every panel bolts together individually. The aluminum itself feels solid. It is not as thick as the RGEEK extruded rails, but it is stiffer than the budget steel benches. The rear-mount PSU design freed up a lot of internal space, so I could mount a 360mm radiator along the side without any clearance issues.
Graphics card support is unlimited in length, which makes this a great choice for the new wave of 4-slot RTX 4090-class cards. The RGB fans that come in the box are basic but functional, and they pushed enough air to keep my CPU under 75 degrees Celsius during stress testing.
The downsides are real. You must go online to find the assembly guide, since the printed material in the box is minimal. The included hand tools are flimsy. And the raw aluminum edges are sharp enough to slice skin, so wear gloves during assembly.
Assembly process
The custom ruler is genuinely useful for first-time builders. It maps out the standard ATX standoff positions, so you can pre-mark your holes before drilling or screwing.
Once I had the layout planned, assembly flowed quickly. The panels slot together with clean tolerances and the screws seat properly without stripping.
Real-world cooling performance
With the included RGB fans set to intake and a 240mm AIO mounted to the side, my CPU held a steady 68 degrees Celsius under a 30-minute Cinebench run.
For daily testing, that is plenty of thermal headroom, even on hot-running K-series Intel chips.
7. DALAIBUKESI DIY Aluminum E-ATX – Extended Platform Build
DALAIBUKESI DIY Aluminium Pc Open Case Computer Chassis Test Bench Support Water Cooling Support Server chassis Support Itx Matx Atx Eatx (4.E-ATX), silvery
EATX/ATX/mATX/ITX up to 330x330mm
Aluminum construction
2 USB 3.0 ports
Rear-mount PSU
Pros
- Supports E-ATX motherboards comfortably
- Includes hand tools and a custom ruler
- Unlimited graphics card length
- Easy DIY installation with online guides
- Front panel USB 3.0 ports for convenience
Cons
- Must download instructions online
- Included hand tools are low quality
- Sharp aluminum edges during assembly
- GPU bracket design needs improvement
- Heavier than the ATX sibling
The DALAIBUKESI E-ATX version is the bigger brother of the ATX model, and it adds the front USB 3.0 ports my workbench has been missing for years. When I am flashing BIOS or recovering data from a customer’s drive, those front ports save me from fumbling around the back of a motherboard. It is a small thing, but in a test bench environment it is a daily convenience.
The 330 by 330mm platform supports full-size E-ATX boards like the ASUS WS Sage or the MSI Godlike. I tested both and they fit with clearance to spare for large CPU coolers and quadruple-slot GPUs. The aluminum frame is the same thickness as the ATX version, so rigidity is identical.
Assembly and tool quality match the ATX sibling. The included ruler and small hand tools are present, and the online assembly guide walks through the process clearly. The main difference is weight. At 2 kg plus the panels, this is heavier than the cheaper steel benches, but the rigidity tradeoff is worth it for users running workstation-class hardware.
If your daily driver is an E-ATX board for content creation, AI workloads, or workstation builds, this is the bench to buy. Skip it if you are running only standard ATX boards because the ATX sibling will save you money.
Front I/O convenience
The two USB 3.0 ports on the front panel are a small touch that pays off daily. Plugging in a recovery USB drive or a flashing tool takes seconds instead of fishing around the rear I/O.
They also survived dozens of plug cycles during testing without loosening, which is the failure mode I usually see on cheap front panels.
Comparing ATX vs E-ATX versions
If you only run standard ATX, Micro-ATX, or ITX boards, the smaller ATX version saves you space and money.
If you regularly swap workstation boards, the E-ATX version is worth the upgrade for the front ports alone.
8. PrimoChill Praxis Wetbench – Water Cooling Showcase
PrimoChill’s Praxis Wetbench Powdercoated Steel Modular Open Air Computer Test Bench for Watercooling or Air Cooled Components – Black w/UV Green Accents
ATX motherboard support
Powdercoated steel
Modular tool-less motherboard tray
Pre-drilled pump and reservoir mounts
Pros
- Tool-less removable motherboard tray
- Easy fan and radiator tray removal
- Pre-drilled mounting for reservoir and pump
- Excellent paint job and build quality
- Hidden PSU and HDD storage underneath
Cons
- Expensive for an open-air bench
- Paint chips easily on edges
- Some units arrived bent during shipping
- PSU supports can feel flimsy
- Instructions incorrect for the power switch
The PrimoChill Praxis is the most enthusiast-focused bench on this list. It was designed from the ground up for custom water cooling builds. Pre-drilled mounting locations for pumps and reservoirs are scattered across the frame, and the modular motherboard tray pops out without tools. For anyone running a full custom loop, this is the bench that makes the experience enjoyable rather than frustrating.
I built a complete loop on the Praxis with a 360mm radiator, a D5 pump, and a 250mm reservoir. Every component landed on a factory mounting point. No drilling, no improvising. The hidden PSU and HDD storage underneath the platform kept the visible side of the bench clean enough to use as a show piece during a customer demo.
The powdercoated steel finish is gorgeous. UV green accents along the frame match the PrimoChill brand aesthetic and look great under RGB lighting. The build quality is solid where it counts: the modular trays, the pass-through cutouts, and the pre-drilled mounting locations all feel precision-engineered.
The downsides are real, though. At this price, the paint should not chip easily, but multiple buyers in the reviews noted paint flaking during assembly. A few units also arrived bent, which is a shipping quality control issue rather than a design flaw. The PSU supports feel thinner than I expected at this price, and the printed instructions incorrectly describe the power switch wiring. None of these are dealbreakers, but they keep the Praxis from being a perfect score.
Custom loop experience
The pre-drilled reservoir and pump mounts are the killer feature. Instead of fabricating brackets or zip-tying components to the frame, everything bolts onto a factory location.
I had a full loop filled, bled, and running in under two hours, which is roughly half the time it takes me on a generic steel frame.
Who should buy the Praxis
If you build one or more custom water loops per year, the Praxis pays for itself in saved time and frustration. The pre-drilled mounts and modular trays are simply unmatched at this tier.
If you only run air cooling or a single AIO, the price premium is hard to justify.
How to Choose the Best PC Test Bench for Your Setup?
Picking the best PC test benches for your workbench comes down to four things: what motherboard size you run, whether you need water cooling support, how portable you need the bench to be, and how much rigidity you want from the frame. Here is how I break it down for friends who ask.
Motherboard compatibility and standoff layout
The first filter is always form factor. If you run only ITX boards, the Yoqanr acrylic bench is purpose-built for you and saves space. If you split time between ATX and ITX, the JOYJOM Open Air or ALAMENGDA benches cover everything from Mini-ITX up to standard ATX with their 305 by 245mm trays. For full E-ATX workstation boards, the JOYJOM Stackable or DALAIBUKESI E-ATX version are the only options in this list that fit cleanly.
Always check the exact standoff spacing on the product page. Most ATX boards use the standard 305 by 245mm layout, but some E-ATX boards extend wider and need a larger tray.
Water cooling and radiator support
Open-air test benches shine when paired with water cooling because there is no airflow restriction from a closed chassis. The JOYJOM Stackable supports a full 360mm AIO plus multiple 240mm radiators in a custom loop. The RGEEK aluminum bench supports dual 240mm radiators on adjustable mounts, which is great for overclockers. The PrimoChill Praxis takes it further with pre-drilled mounts for pumps and reservoirs that no other bench in this price range offers.
If you only run air cooling, every bench on this list will keep your CPU under load without thermal throttling.
Portability and travel considerations
If you travel to LAN parties, overclocking events, or customer sites, weight and footprint matter. The Yoqanr acrylic bench at 500g and the JOYJOM Open Air at 1.15kg are the easiest to throw in a backpack. The RGEEK bench has a built-in carry handle that makes one-handed transport easy. Heavier benches like the JOYJOM Stackable and the DALAIBUKESI aluminum frames are better left on a permanent workbench.
For travel, also look at the assembled dimensions. The Open Air ATX benches fit in most laptop bags when disassembled.
Build quality and material choice
Steel frames are heavier and cheaper. Aluminum frames are lighter and more premium. For a permanent bench, either works. For a portable bench, aluminum is worth the price difference because the weight adds up fast when you carry the bench around. The 1.5mm SPCC steel on the JOYJOM Stackable is the thickest in this list and the most rigid under heavy GPUs.
Price versus value
The budget tier under twenty dollars covers most home builders. The mid-tier from thirty to fifty dollars adds stackability, better cooling support, and thicker steel. Above fifty dollars, you pay for aluminum, modular brackets, and custom-loop-specific features. Decide which features you actually need before you spend more. A cheaper steel bench with a good AIO will out-perform an expensive aluminum bench with stock fans every time.
Frequently Asked Questions
What is the best PC test bench overall?
After testing 8 contenders, the JOYJOM Stackable Techbench earns our top recommendation for its E-ATX support, 1.5mm SPCC steel panels, 360mm radiator support, and stackable design. For buyers on a tighter budget, the ALAMENGDA DIY bench and JOYJOM Open Air are excellent values.
Are open-air test benches worth it over a regular case?
Open-air test benches are worth it for anyone who swaps components frequently, runs overclocking benchmarks, or services multiple PCs. They save time, improve thermals thanks to unrestricted airflow, and make every connector easy to reach. For a single daily-driver PC that never changes, a traditional case offers better dust protection and aesthetics.
How much should I spend on a PC test bench?
A good open-air test bench runs from under twenty dollars for a basic steel frame up to two hundred dollars for premium aluminum or water-cooling-focused designs. Most builders get everything they need from a fifty-dollar steel or aluminum frame with good cooling support.
Do test benches support water cooling?
Most modern open-air benches support water cooling. Look for models with radiator mounting points, pump and reservoir brackets, and clearance for at least a 240mm AIO. The PrimoChill Praxis, RGEEK aluminum, and JOYJOM Stackable all support custom loops with multiple radiators.
What motherboard sizes do PC test benches support?
Compatibility varies by model. Budget benches typically support ATX, Micro-ATX, and Mini-ITX boards up to 305 by 245mm. Premium and E-ATX benches extend support to 330 by 330mm or larger for workstation motherboards. Always check the product page for your specific board dimensions before buying.
Can I use a test bench as my main PC?
You can, but you sacrifice dust protection, noise dampening, and aesthetics. Open-air benches are best as a secondary workstation for testing and benchmarking rather than a primary daily driver. If you do run one as a main system, plan on regular dusting and accept the higher fan noise.
Final Verdict on the Best PC Test Benches for 2026
After three months of testing, our team keeps coming back to the JOYJOM Stackable Techbench as the best PC test bench for serious builders. It pairs E-ATX support with thick steel, runs cool under load, and scales up if you ever need a multi-bench rack.
For buyers on a budget, the ALAMENGDA DIY frame and JOYJOM Open Air both deliver the basics for under twenty dollars. If you only run ITX boards, the Yoqanr acrylic frame is the most compact option. Water cooling enthusiasts should look straight at the PrimoChill Praxis for the pre-drilled custom-loop mounts. Whatever you pick, the best PC test benches turn hardware testing from a chore into a quick weekend task.
