So, I started buying and selling used gear, and I really needed a test bench for testing GPUs. What I managed to build can, of course, be used for testing other stuff as well, like SSDs, monitors, USB gear, SATA HDDs (and maybe the old HDDs as well? I am not sure what all the old connectors are for, sorry ^_^)). The PC is assembled using only used parts bought on a local buy-and-sell website.

Now, if Lian Li and all the AliExpress sellers think that I will spend a 100 bucks or more on an open case, they are insane! (JK no hard feelings I'm just stingy). I just wanted something simple where I can pop a GPU in and out as fast as possible.

What you see here is some industrial ITX mainboard that uses a dual core AMD Athlon 64 X2 3600+ CPU and 2gb of DDR2 SODIMM RAM. It has a 16x PCIE slot (2.0 I believe), which is good enough for most GPUs that I test (stuff up to the GTX900 series and 1050 ti cards). I have a USB dongle plugged in for a Logitech Wireless keyboard with a touchpad on it. It is small and compact, which was REALLY important for me as I don't have a lot of space for an additional PC. I am literally keeping the two things on my table and I have two cables coming from my monitor so I can switch between my main PC and my test bench. A KVM switch was an option, but all of the ones with an HDMI and USB ports were too expensive for me (they are only 35 bucks IF you can find them locally, but I don't want to spend 30 bucks on a test bench where I test cheap and old cards on which I make 30 or 40 bucks profit). So I used a DVI cable I had lying around and bought the keyboard for 12 bucks used.

Underneath the mainboard is a 120gb SATA SSD with Win10 on it. I have a few simple benchmarking and ID tools on it, namely GPU-Z, DDU, Heaven Benchmark and UserBenchmark. I am not looking for the craziest and most precise benchmarks, I just want to see if the thing works as intended.

Lastly, I got an LC Power PSU with 600 Watts and 2 PCIE power connectors (1x 6 Pin and 1x 8 Pin that can separate into a 6 pin as well). I got a few SATA and Molex adapters that I can use if the GPU needs more than that, but its pretty much enough for me.

I managed to connect all the parts with a bit of tape and a few cable ties. its pretty sturdy considering everything. I am very happy with the results and I have managed to test about a dozen GPUs since I have assembled it. No longer do I need to chose between selling a GPU that I didn't test beforehand and opening my personal PC and dealing with drivers to test something I am going to sell anyway.
