Since the Mac Pro is one of the most versatile apple computers, I've been very tempted to buy a refurb one as a tinker project just to get inside and learn more about it. Been looking at the lowest model they have in store: http://store.apple.com/us/product/FB871LL/A At this time it holds no real use for me as I already have 2011 models of the 13" MBP and Mac mini and they do everything I need so far. But I'm going back into school for computer science and want to know as much about the hardware as I do about the software when I'm done. I've built my own PC gaming towers before so I have a moderate knowledge of hardware repair, but am by no means an expert. I don't do it for a living, but am interested in applying for a genius position at my local store while I attend my last few years of college. My main reasons I'm looking into this route 1) To be proficient in Mac repair 2) To have a "backup" computer to last me for a while past my mini's life expectancy. 3) Eventually turn into a media back-up for iTunes, FCPX projects, Aperture Library, Sketchbook Pro projects. 4) To own a freakin Mac Pro I'm soon coming home from my deployment to Afghanistan and will have some extra money to budget for this before school starts. I'm just a very curious individual when it comes to computers and Mac's have actually kind of stiffled my curiousity to open them up and work on them aside from changing hard drives and ram (except for my old mini I used to have, that one was fun to take apart). Does this sound too irrational? It sounds like overkill for what I want to do, but I'm hoping I will eventually make a good use for it in my home or work.
