If the case is bent in the volume control area you can just use pliers to unbend the case. Be careful and use a cloth pad to avoid scaring the case. In my case (pun intended) the thin aluminum above the cutout part of the case was bent and Apple wanted almost as much as a new one to repair it.
I have a1466 mid 2013 that had water damage. After replacing the battery the 1466 has come back to life however, the airport card seems to be dead now having spent a hundred dollars I'd hate to spend much more to make this machine functional again. Does anyone have any suggestions.. If not repairing then a reliable place to purchase an airport card. Thanks, Daniel Butts
