I was mildly disappointed with Vavles pricing, so I told my nephew i'd make him a Bazzite system. He plays simple games.
Specs: Ryzen 4650G 450W PSU B550 Asrock ITX board 16GB DDR4 @3600MT/s 1TB PCI-e 3.0 Nvme Coolermaster 240 AIO (somehow crammed in) Silverstone SG-13 case
I love the SG-13, nice little case and cheap, doesn't require expensive PSU or low profile GPU either. I've built 2 of them, and I know my sister is still using hers with an i5 8400 and GTX 1070. IDK if the other one is still in use but I think it had a 10400 and RTX 2060.
