I have an old hand-me-down laptop from a relative. It's from 2011 and is a Core i5. The screen is terrible, but otherwise it's perfectly capable. I couldn't call it a "project," but I've installed a music player (Rhythmbox, but pick whatever software you like) and hooked it up to some premium speakers. It's the best music player I could hope for -- it can play literally any format, doesn't phone home, and uses very little energy.
