In our final part of our Mac Pro coverage we look at its upgradability and performance under Windows XP By far the biggest problem with upgrading the CPUs in the Mac Pro is gaining access to them. While Apple made it very easy to upgrade memory, storage and PCIe cards in the Mac Pro, getting access to the CPUs is considerably more difficult. The entire process would be made much easier if we were able to remove the memory cage, but as we mentioned in our last article the standoffs that the cage is screwed into would not remain in place while we unscrewed the cage. To make a long story short, we weren't able to remove the memory cage without stripping the screws that held it in place, so we had to come up with an alternative solution; luckily we were able to do just that.
