You tare welcome. In the early 2008 and models before it, the case had to be disassembled and it did void the warranty (as per the manual) but if nothing was harmed inside, then I never heard of a warranty issue being denied. You just had to replace with the original drive before taking in for repairs. They also stated during that time that non-Apple certified RAM would void the warranty as well, and yet again I never heard of anyone getting denied for aftermarket non-certified RAM, although it was possible.
