Not that old but my 2009 i5 750 can still rock most of the games at a solid 1080p. I added a fan and overclocked it to 3.6, some ram and a 1060 gpu. It now serves as our main streaming / gaming computer on the TV and shows no sign of giving up. Overall I’ve spent less than 650$ over 15 years on a computer that we use daily.

Tanks, that’s a really detailed guide. Would it also work as a home server for Nextcloud? I wanna ditch the Google office suite.
