Main Computer:
400mhz Powerbook (Pismo)
320mb RAM
40 GB HD
8mb ATI Rage 128mobility(i think)
Screen is broken so i have it hooked up to a 17" external CRT

Also have an iMac rev.C i believe, used for internet/file server
266mhz
384mb RAM
40 GB HD
6mb Rage Pro(not even recognized by OS X)

Both run 10.3 fairly well so i just dont see any reason to upgrade.
