You are using an M-Box right? You didn't mention that specifically. The reason I ask is not all host cards will play nice with a PCI-based setup like the 001. That SIIG card looks cool. It is bootable which is ideal since you can use a nice fast drive like a Raptor to boot from, and record onto an ATA drive on the Mac's internal ATA bus which is plenty fast for PTLE track counts with a modern drive. also makes bootable SATA cards which work well in G4s, and offers more options on ports, and channels.
