I just received my Dual 2.3 Ghz G5, and I notice that the hard drive is quite noisy. It's working OK, it's just noisy. I had a 1.8 Gig machine with a smaller drive and you could never hear the drive working at all.
Can anyone recommend a quiet 250 gig hard drive? I'm going to put this one in a Firewire case and use it for backup.
