Dilemma: The optical drive has finally died on my 2.2 SR MBP ('aluminum' body style) and I am now well out of warranty, so I'm interested in just swapping an ATA-to-SATA optical bay caddy and HD in its place. The problem, though, is whether this will create problems down the line when my computer's GPU fails (I've already had 1 logic board replacement for the 8600m issue). Would I be able to send in my computer for warranty work with a hard drive in the optical bay, when the time comes? Would they have any reason/grounds on which to reject the warranty claim if I swapped it back out before sending it in? Any thoughts?
