Ok so now I have Decided that I am going to get a 17" MBP with a 2.6GHz processor. I want to upgrade my RAM to 4GB but I would Prefer to upgrade with a 3rd party. I already Know where to Get it I just need to Know if this will void my warranty. Also I would like to know if there is any way to get a 320GB 7200 RPM hard drive installed without Voiding my warranty. And finally I would like to Know if I can Buy Apple Care about 3 months after I purchase the MBP?
