Three T5 Torx screws secure the ectomorphic logic board in place.

Like most recent Apple laptops, the heat sink comes out attached to the logic board. This is nice, as you'll only need to remove the heat sink and reapply thermal paste if you're replacing the logic board.

Unfortunately, like all previous MacBook Airs, the RAM is soldered to the logic board and is not upgradable. Apple does offer a 4GB RAM option at the time of purchase, but if you opt for only 2GB and decide you want more RAM later you'll be out of luck.

Our advice? Go for 4GB.
