If your machine came with a 7mm drive and you are replacing with a 7mm drive you do not need to move the logic board. I installed an Intel 335 240GB drive which is a 9.5mm drive and to get that drive in I did need to bump the logic board out to clear the memory slot brackets. I did not need to remote any other wires or connections as the logic board only needs to move maybe an 1/8" to get the drive to clear the memory bracket.
