Hi friends, Two questions: 1. In thinking about a Mac Pro, if the refurbished product on Apple's page is exactly what I want, should I have any hesitation in purchasing a refurbished Mac Pro as opposed to a non-refurbished one? 2. I assume I would have no problem installing one of these on a new Mac Pro? http://shop4.outpost.com/product/4116853 Thanks, Tabletop.
