My computer was failing frequently so I had it serviced through AppleCare (actually the “Depot” for much less than Apple) and they replaced the logic board. Turns out that iTunes authorizations are tied to the logic board. Without the old motherboard, it is impossible to de-authorize the account for the computer and thus an additional device (the computer with the new logic board) must be authorized (of the five allowed). Of course, I already had five devices authorized so I had to de-authorize all and re-authorize my active devices.

Moral of the story is if you send your mac in for a logic board replacement, make sure to de-authorize the computer prior to service; this will allow you to authorize the computer upon receipt and not consume one of the five authorizations for the phantom computer.
