I'm not sure if I should get an iMac or a Mac Pro - my decision will be based on performance when editing 1080p video in FCS/AE and how loud both systems are. I used to have an old PC desktop box in my room which was so, so painfully loud so, when I would leave it on overnight for rendering, it would be like someone playing the recorder in the corner of my room overnight. Torture. I was wondering what everyone's experience with the Mac Pro's fan noise is, both when idle and when rendering something. I'm also interested in the performance of the iMac. If I got the i7 (27") iMac with 8gb or ram and hooked up an external drive for scratch, would this perform well? I'm trying to learn After Effects/FCS seriously and have not got much experience with them - would the iMac hold up? On top of this, would you guys be able to reccomend a scratch disk? I've basically decided I want either this SSD drive or this raid0 drive. I'm willing to pay more for the SSD but, I'm not sure if it would be worth it/if 128gb is enough (I've never done serious editing on my own setup so I just don't know these things since they have already been done for me at uni) Thanks for your help!
