I have an extra PC I am considering setting up as a "console" using Linux. After a conversation in another community, it got me wanting to look into NixOS because I love the reproducibility aspect and I wouldn't need to have may apps installed that aren't installed through Steam. The other video I shared showed that the NixOS package for Steam isn't updated. So, that is a worry.. But, I'm still reading.

From the comments of that video someone suggested the following: Jovian-NixOS.

It looks good/promissing but it is built for Steam Deck. I would like to kind of clone the Steam Deck experience on a computer with an Nvidia graphics card and intel processor. Still reading/learning.
