Yes, I have both. The desktop is pretty beefy and runs Windows (for now) and is mostly used for games and Adobe stuff. The laptop is a Thinkpad running Linux Mint, and is my couch computer. I use it for normal web browsing type stuff, and for managing my home lab server that sits in a closet in my basement. I also play some lightweight games on it via Steam/proton.
Your post inspired me to pull my old PS3 Slim off the shelf and give it a shot. Fortunately it is one of the ones capable of custom firmware. I successfully jailbroke it and am now running custom firmware, next I just have to figure out how to do anything useful with it, lol.
