Just one connector and two screws sets the little system speaker free.

iMac and MacBook speakers seem to be getting bigger all the time, but this one looks about the same size as in older Mac minis.

Beneath the speaker, we find some antenna cables, but unfortunately no modular AirPort card—in what is becoming a trend, these are socketed right to the main board.

Alas, AirPort cards are just a distant memory now that logic boards have assimilated all wireless functions.

From here we set to work freeing the heatsink, twirling away Torx screws and exposing the paste-y (soldered) CPU.

One last screw, and the port cover is free, uncovering ... the ports. As it departs, it takes some antenna hardware with it.
