My gaming PC sits next to the TV in my living room and I use it like a console, I have one of those cheap blutooth wireless keyboards with trackpad for the really basic iteractions and then I just use a game controller for playing games.

Windows 11 has been fine for me, I don't interact with it much other than seeing it for a bit when launching games.

I honestly wouldn't mind giving Linux a go, the only downside is I made the mistake of buying an nvidia graphics card, I'm not sure how much of a pain it is these days but last time I tried it was a bit of a nightmare - the general wisdom at the time was to go with an AMD card.
