I've built a small PC with erying es 0000 Chinese motherboard and a Radeon 7800xt. I've loaded ChimeraOS onto it. I essentially now have the steam machine I always wanted.

I plan on making it smaller but the GPU is quite big. I'm thinking about getting the minisforum bd790i next and moving to an itx case that will support the 3 slot AMD Nitro+ GPU.

From the software standpoint, it's awesome. You download the game and it runs. Minimal fiddling. Just beat silent hill 2 on it and now in repaying RE4.

I can't recommend these erying motherboards to everyone, it's actually quite a big gamble IMO. The minisforum is probably a safer bet.

Follow up to this: just bought the minis forum BD790i. I'm using it now with the sapphire nitro + Radeon 7800xt. I've installed Bazzite now and I'm giving it a run for its money.
