Built July 2002.. upgraded in August 2004 (new processor, more ram).
It is my homebrew linux box (that I am ashamed to admit I didn't have the money for much more than it is) :
Athlon 1300 (1.3Ghz.. I had a 1.2Ghz Duron, but the L2 Cache went bad on it, and I wanted a faster processor in 2004, but I didn't want to get a new Motherboard)
512megs of RAM (back in 2002 I put in 256 megs)
6gig Harddrive (I forget the brand, my 80gig IBM Deskstar suffered a horrible head crash)
ATI Rage 128 (128 doesn't mean 128megs.. nope.. it is a horrible 32meg card)
Creative 52X CD-ROM Drive
Toshiba DVD/CDRW Drive
... now you know why I want to get a MacBook Pro in the Fall.
