Last year I was looking into a new computer and I got the feeling that the iMac was the best bang for your buck, hands down. Since the new Mac Pro came out, it seems like the iMac vs Mac Pro threads always point to the Mac Pro, especially since I am interested in SSD. So now I am wondering which model I should get. SSD... Do the older Mac Pro's support SSD? I know this was touted as a "new" feature? Does that mean a refurbished MP will not have the ability to easily install SSD unless it is the newest revision? This Mac Pro on Amazon is the best seller (Amazon Link). Would SSD be easy to install there? Also what other advantages would I have by buying the newest version compared to a slightly older model on Amazon?
