OK so I was a little bummed when I found out my trusted Mac Pro could not use Lion 10.8. I have been thinking of getting a new MacPro but since they are really ***** expensive, I am considering going with an iMac 27". In my current MacPro I have all the bays filled with 1 TB to 3TB drives. One drive is dedicated to Music files, another for ripped Movies and another for my extensive porn collection (pictures and video) and another drive for regular family photos and so forth. So anyway, what I am thinking is, could I just always use the MacPro in Target Disk mode? I have used it before when transferring files and recovering from a disk crash. Would the Mac Pro go to sleep when the iMac goes to sleep? I know this tower is basically a big heater when running during normal use and is a huge energy hog. Is there anybody out there that has done/currently set up this way? And before you say buy some enclosures I will say the multi drive enclosures are $500-$600 and even single ones can be a pretty penny also and times that by 4. If I can keep using what I have but in a different way that would be great. Thanks for your input
