What should I do with my old computer?

I have an old computer that I just can’t seem to give away or make use of. It’s an old Athlon 64 2.4 ghz with a gig of ram, 160 gigs total hard drive space and a 256 meg Radeon X750 video card.

I originally had set up as a TV pc, but once I got a long enough cable I hooked up my main workstation to the television with much better results. Now it just sits in my closet taking up space. It’s far from bleeding edge up-to-date, but it’s nice enough that I don’t want to just throw it out.

I had given some thought to finding a cheap, small LCD monitor and making it into a really elaborate digital clock, but it’s way too loud to have running all the time.
