Hello all, I'm about to purchase a new Mac and I have a question about purchasing extra RAM. I will probably purchase the Mac directly from Apple to receive the education discount. I have seen many posts here suggesting that I do not purchase the extra RAM from Apple, (because of the cost) rather I should buy it from Crucial. My question is this. If I buy the extra RAM separate and install it myself, would that not void the Mac's warranty from Apple? I want to buy AppleCare also, but if opening the case to install the RAM voids the warranty, what choice do I have other than ordering the extra RAM from Apple and having them install it? Thanks for your help!!!
