There are a few differences to account for: * The multitouch cable connector on the upper case has been relocated in the Rev.b machines, which makes connection difficult. * The black shielding on the lower case is slightly different. This may or may not affect compatibility. * The audio board is not compatible between models. You would need the correct audio board and cable for the appropriate logic board. * The hard drive connector, as you noted, is different and must be worked around. * The fan/heat sink are 2 separate pieces in Rev.b. * The airport/bluetooth cable is slightly different as well. I haven't actually performed the swap; these are just the physical differences. Good luck!
