At my college we're upgrading an Xserve G5 (RackMac3,1) to be a file server for some courses. Currently it has one sled with a 75GB drive. Obviously, this isn't enough. I've tried some Googling on this matter and I'm hearing a ton of different stuff - custom firmware, size issues, etc. So, for anyone who knows, what's the actual lowdown on this machine. We want to put in three 2TB drives using three standard sleds, replaced with third-party drives. Is this possible?
