The reverse of a question I asked on here a while ago.
It’d be interesting to see if you could install the Steamdeck’s OS on a Steam Machine.
Valve has not yet put in the effort to create a generic version of SteamOS because their focus is on the Steam Deck right now, but the community has.
Bazzite has been made to look and feel almost exactly like the Steam Deck and can be installed on any PC (AMD GPU recommended). Give it a shot!
