Which distro of Linux?

I had an old pc laying around I tried installing Foldix on but that failed mierably. Anyway...

What distro of linux should I use for this pc (specs will be listed below). I intend to use it for folding and as a backup PC and something to use to read directions on incase I need to do something to my PC I can have directions right here.

533MHz PIII-based Celeron
256MB SDRAM unknown speed (probably PC100)
ASUS MEW-VM
10gb hard drive
no video card
Linksys LNE 100TX network card (no onboard LAN)

If anyone could suggest a Linux distro and direct me to some Linux dirvers for this thing I... uhh... will send you an e-cookie and click the thanks button!

 

So I'm assuming you want fast and light. Give DSL a shot. http://damnsmalllinux.org/

Puppy Linux is another to look into.
