OK so I'm buying a 'new' 2010, overpriced, 12 core Mac Pro with the latest 2 year old Westmere CPU's (sorry couldn't resist, I'm very bitter), unfortunately I have no choice, I desperately need a speed bump and I've looked into every alternative, even Windows. I've never been so unenthusiastic about dropping £4K, but apparently I do get a free iPhallusPro to adhere to my forehead. Anyway, I plan on upgrading it with some Crucial RAM and a SSD. My question is will this void my AppleCare, if anything were to go wrong with this system and I had to take it to Apple would I have to reinstate the Apple RAM and remove the non Apple SSD, so it is same as sold? Ideally I would like to get some money back on the Apple RAM (although there will be a huge difference between the price I pay Apple and the resale price I can get for it, on the same day!), but need to know whether it would be best to hold onto it for AppleCare? Thanks, One other thing: Apple shop 12 Core, RAM = 12GB Refurbished 12 Core. RAM = 6GB Surely this means, a 12 Core in the Apple shop could be sold with 6GB of RAM, without problem? I'm probably going to end up getting a refurb, for the faster CPU's of couse, but also because I don't want to pay for additional Apple memory that I'm not going to use, I know its not much, but 6GB less is about £200 saving = 16GB Crucial Kit. Crucial 4GB = £32 Apple 4GB = £120 (You've got to be kidding!) Apple go to every length they can, to squeeze every penny out of you.
