Let's see. Marvin had a socket A in some generic black server case. I wanna say I built her in 2k3. Deep thought (socket 939) got a MountainMods U2UFO 2 years later, then moved her into a Antec 300 when I built Earth into the same U2UFO around 2k9. Nevermore is under construction in a Cosmos 2 right now. Project log is currently in the water cooling subforums. Almost complete!
EDIT: and Earth was moved into a Rosewill case for space considerations, while the U2-UFO is currently collecting dust, and Deep Thought finally ave up the ghost...
