I am planning to buy a Macbook 2.4ghz after wwdc and I am planning on upgrading the RAM and maybe the hard drive. I know I want to upgrade the RAM I was wondering if I should have Apple do it when I buy it for $90 (thats how much it says when I customize it on their website with student distcount) or if i should buy some somewhere else and install it myself? I don't know how hard it is or if it voids your warrenty or anything... I was also maybe planning on upgrading the hard dirve, I was wondering if doing this will boost my speed or not because if it doesn't i probably won't need bigger than the 250g hard drive. I can upgrade to the 320g hard drive for $67 at apple store or should i get my own and install it if i need it? Is this hard or does it void your warrenty? thanks for any help!
