This is awesome. I used to build a lot of stuff with various single-board computers (Raspberry Pis, etc) but realized I could get way more performance and expandability with these mini PCs if the form factor didn't require it.
One other thing I'd be interested in: not just mini PCs but used office workstations. I realized that many offices were selling old workstations that were often just a few years old with things like dual Xeon chips and 64GB of RAM or more with support for a few hundred GB for only a few hundred $. Things like 2ish generation old HP Z400/Z600/Z800 series. They make for great home lab virtualization machines and can often support 2+ GPUs and a boatload of additional peripherals. I'd love to see something like this that lets you find those as well
I was actually going to make one for workstations, since that is what I thought the best deal was for my home server. Then I did some research, and realized mini pcs are a better deal now. Still might build it though.
