The 2013 Mac Pro has been torn down, and rather remarkably, in addition to it being surprisingly good value for money, it's actually fairly easy to fix and upgrade! Upgrading the Mac Pro's RAM is easier than your desktop or laptop PC, and it's also fairly easy to upgrade the Intel Xeon (Ivy Bridge-E) CPU. All of the major components are modular and can be easily removed, though proprietary connectors mean that you can't upgrade the graphics cards or SSD with off-the-shelf components. Overall, iFixit gives the Mac Pro a repairability score of 8 out of 10; much, much higher than the latest MacBooks, iPhones, and iPads.
