Hi there, I am about to purchase a MacPro, but I have some questions about SILENCE. I would like to purchase additional HDDs which are: -74GB Raptor (from OWC) -500GB Seagate 7200.10 with 16MB cache (from OWC) completing the 160GB Stock HDD (from Apple) I am concerned about noise, and heat, and fans kicking in, as I will be sleeping right next to it. Anyone who got one of these HDDs would be pleased to quickly mention their perfomance (transfer rates, ect. but not in RAID) and noise/heat on a MacPro. I really want the raptor, but if it's tooooo noisy and the fans kick in, then I'll check something else. Thanks!
