Thanks for the OWC tip. What about a bigger hard disk? I assume the Mac Pro can take any SATA-3 hard drive, right?
No problem. I decided to wait a day to see if OWC was going to put out updated FB-DIMMs. Even with ADC discount Apple's premium on FB-DIMMs is unbearable by a factor of 3x.
You should be able to use any SATA drives. I plan on adding a 150gig Raptor and using the 320gig as a dedicated Time Machine drive.
