I currently use a 2009 Unibody MBP 17" (top of range 2 years ago or so) I want a mac pro but understand its likely to come out q1 2012. Dont really want to buy a MP now when a refresh is imminent, i going to be doing alot of filming from early November, so could do with faster renders, and quicker compositing. Ill be using FCP 7, Motion 4 and After FX CS5 - Id like to do complex 3d graphics / tv title sequences in motion 4 / After FX and have much quicker render times etc than the laptop. I edit in Apple Pro Ress 422 LT. I have just bought a 4tb G Tech Firewire Raid (2x 2TB drives) so can use that for video files. With the mac mini server, does the dual 500GB work as a Raid? Would this generate more heat? Or does it just show up as 1TB or can you have 1 x 500gb and 1x 500gb thats a back up? I see this as a stop gap until the MP has been out for 3 months or so (iron out any issues with the likely new design) - see how things pan out as may need to move to london anyway. Also, how easy is it to upgrade the mac mini yourself / what cant be upgraded easily? Heat issues as ill be doing alot of rendering / graphic intensive stuff?
