What to do with a fairly decent unused computer

Question

I have a fairly decent computer running at 2.4ghz single core, 1gb of ram, 200gb hard drive and 512mb video ram, I'm upgrading to something much better, Is there anything useful I can do with this because I really don't feel like selling it and would like to make use of it.

Answer 1

Send it to me :P

Really though, use it as a file server, or perhaps a small videogame server or something.  

Answer 2

Give it to a family member or friend!

Lols, I'm not sure either, I have a fairly decent comp sitting next to me also, which I will be giving away to my friend.

Only thing I can think of is to use it as a backup pc/ and store all your entertainment/docs/etc... in it.
