Dual 1.25 G4, 2GB RAM, OSX it rendered in 2:25. Not bad considering the G4 (and G4 RAM) are dirt cheap compared to the G5's. I just got this machine a few months ago, saved myself a boatload of coin over going with the hi-end G5 with same amount of RAM. I ordered it with the GForce 4 Titanium graphics card, and it absolutely screams in interactive render. Hi-poly models like the DAZ mil dragon or V3 don't even phase it.
