The new Mac Pro's highly customized design may look like it's a pain to fix, but don't be fooled -- it's friendlier than you think. An iFixit teardown of the workstation has revealed that it's easy to take apart, and that several components can be replaced without going through Apple. It's also more upgradeable than you'd expect. iFixit has confirmed OWC's discovery that the Xeon processor is replaceable, saving buyers over $1,000 if they splurge on a 12-core chip. Other findings? The PCI Express-based SSD looks very familiar, and the entire system is very power efficient; despite the high-end CPU and dual graphics cards, the Mac Pro only needs a 450W power supply. No one will mistake Apple's machine for an easily expandable gaming rig, but it's clearly built with serviceability in mind.
