Ok, so I know on my old mid 2007 Macbook (non unibody) you could change ram and I think hard drive and not void the warranty or apple care. Are you still able to change the hard drive (or ram) on a unibody Macbook Pro and not void the applecare? Or since it probably isn't near as simple does it void warranty? Pondering buying a macbook that is new but some one already installed a new and better hard drive (non apple supplied one as it has a faster speed). But not sure if that already also voided the normal Apple warranty and pretty much made it impossilbe to get applecare for it.
