For my Mac Pro, I’m going to have OWC do the CPU upgrade, as I’m good at losing small screws and similar. However, it’s as yet unclear when OWC will offer a CPU upgrade service.
Also, to prevent bending the memory latches (I’m guilty), OWC now ships a plastic spudger tool with each kit:
OWC 1866MHZ DDR3 Kits are available now for upgrading all of Apple’s new ‘2013’ Mac Pro 3.5GHz 6-Core, 3.0GHz 8-Core, and 2.7GHz 12-Core models to up to 64GB.
The Spudger tool now included with all OWC Mac Pro Upgrade kits is the same type of tool used by Apple technicians to aid in the disassembly of iPods, iPads and iPhones without damaging or scratching any other component.
