OK - I've been accessing the 3 TB of disc on my iMac Corei7 via gigabit ethernet to my old PowerMac G5. Looks like the power supply in the G5 finally bit the big one the night before last and that machine is totally inoperative so I'm trying to figure out how best to replace the capability. Ideally, what I want to do is take the two formatted 1.5 TB SATA drives OUT of the G5 case and put them into some kind of powered case that can be connected to gigabit and then I can access them like I used to thru the G5. Secondarily, it would be a Firewire 800 powered case but I'd prefer gigabit speed. I've taken a cursory look around but it looks like most of the cases I've seen are: (1) won't take already formatted drives. (2) aren't Mac compatible. (3) insist on some kind of internal auto-format of the existing drives. I just want to take the existing drives as is and pop them on my subnet and be able to access them at gigabit speed. Is there such an animal?
