What can I do with an old Compaq PC other than recycle it?

My parents have an old Compaq Presario SR1950NX that works perfectly fine, but hasn’t been used in at least 15 years. Obviously I can’t connect it to the internet with Windows XP, but before I recycle it I thought I’d see if anyone had any cool ideas for how I could use it. I’m sure I could find Linux distro that would work, but I don’t really need another desktop PC in the house.
