    • Excellent buy, easy to assemble, easy to use, very sturdy
If you're looking for an open air PC case, I would highly recommend these units. Enjoyed them so much that I ended up buying another. They are sturdy, well formed, and fit an E-ATX board and a full length GPU (5070 OC) with room to spart. Assembly is quick and easy and it's well worth the money. If I had anything negative to say about the case, I wish there was a bit more mounting holes for optional fans along the back rail and/or if the case was maybe 1-2" deeper so I could fit a 200mm fan against the back rail. Additional accessories, such as a riser option that mounts to the top would also be nice but don't let my wishes stop you. ... show more

    • Solid open chassis

I could not have been happier with this case. It looks good. With parts installed, ita very rigid. Provides full accessibility to everything. The instructions are a bit lacking, but easy enough to figure out.

    • Works fine - instructions could be clearer.
It works as expected; its sturdy. The only thing I could complain about is i wish the instructions were a little clearer; I almost threw away the little piece that helps secure the PSU. I would buy again if I was looking for another one.

    • Great open air case.
This case is exactly what I had been looking for, it fits great into my desk closet and lets me have two pcs with great air flow, improvements of 10 to 15 degrees celcius. The assembly is easy and sturdy once put together.

    • Great for test builds and open-air hardware projects
This open-air test bench is very useful for PC building, troubleshooting, and hardware testing. It makes it much easier to swap parts, test motherboards, check GPUs, or work on systems without constantly installing and removing everything from a closed case. The open layout is also helpful for airflow during temporary bench testing. This is not the same as a normal enclosed case, so it is best for a workbench, lab, server experiment, or temporary build rather than a dust-protected everyday desktop. But for people who regularly work on hardware, it is a practical and flexible frame. I was satisfied with it. ... show more

    • Good test bench
Nice test bench. Pretty rigid once all screws are tight. The included power switch is nice, but would be better if it came with a clip so it could be mounted on the frame instead of being loose.
