HELP! Need advice with obsolete computer!

Hi guys, I have a very old computer which I just took out from the store and here are the specs: Pentium III 650 MHz 96MB RAM 8GB HDD 16MB ATI Rage 128 GL Hercules Fortissimo II Gamesurround Soundcard Originally, I intended to turn it into a Tivo-like media centre using Ubuntu & MythTV + a TV Tuner card, but I think my specs might not make it. So now I'm thinking of turning it into a webserver =) Anybody has any experience in this? Any ideas on which Linux distro I should use for such a low-spec machine?
