Hi All Sorry if this is already posted but I thought that this was interesting. http://www.970eval.com/ Maple - IBM 970FX and CPC 925 Evaluation System Its an ATX Mobo that uses dual 970FX CPU's (basically a G5) It runs linux as its OS. It should therefore be able to run Darwin. I wonder if this is how the G5 started its life. Notice that board can address the full 8 ddr slots (8 gigs of ram) Also take a look at the PCI Slots, its got the PCI-X slots http://www.coolinnovations.com/ These are the people providing the cooling I think for the board. Where's the AGP Slot ?
