Hi, I have a early 15inch 2008 macbook pro (NonUniBody) - 2.5 core 2 duo, 4gb ram, Lion OSX 10.7.4, 512 8600mGT and I've used two 7200rpm 500gb hard drive and thinking of making jump to SSD? Which SSD would be compatible with my early 2008 MBP? Also, would it be hard to assemble? I swapped out the internal hard drive twice, is it a similar process? Thanks!
