Well I dont think that a retina iMac will suffice. I had a mac pro for my home music studio. The point of it was to be a beefy machine that was plenty expandable had lots of disk space and was quiet for the horsepower it provided. Mac pros fit that bill perfectly. it was easy to load them up with fast server class hard disks plug in your audio interface, any DSP boards, dongles or whatever else was required and then you forget about it (that is, until you see your electric bill the next month...) I got the 2008 octocore Mac Pro and did just that and ran both mac os and windows on it until I finally sold it last year(regrettably to help pay for personal circumstances as well as a lack of time for music production) and never had a single issue with it. THAT is what I spend the extra money on, I want a beefy computer that will last me 5 years. That is what the PRO audio crowd wants them for. I would imagine its not much different in the graphics/video arena either.
