G4 compatability
I probably spelled that wrong... anyway, I've been eyeballing one of these for a potential hack. My question is, are these mac compatible as far as wiring and space between slots goes? It's either that or a single AGP riser and a single PCI riser, but the 2 PCI slots would help.

The riser would fit on the motherboard, but the motherboard slots will not line up in MOST rackmount cases. I wanted to put a Gigabit in a rackmount case i got for $20, but the slots would not line up, and if i wanted them to line up i would have had to buy a $30 AGP riser.
