Mac mini (PowerPC) Wireless Interface Board Replacement

Introduction

This board connects the airport card to the logic board.

If your mini does not have Airport installed, then skip this step.
Grasp the Airport antenna board and lift it off of the two plastic posts holding it in place. You may need to push back the black plastic tab jutting through the lower left corner of the board.

Remove the yellow tape securing the power button cable to the black plastic framework.

Remove the three black Phillips screws securing the plastic framework to the logic board and lower case.

Grasp the optical drive and mass storage unit in one hand and lift up enough so that you can see beneath it.

If your mini has neither an Airport card nor a Bluetooth board, you can simply lift the optical drive up and away. Otherwise, you need to disconnect the Airport and/or Bluetooth antenna cables first.
With your free hand, pull the Bluetooth cable up from Bluetooth board and unplug the Airport antenna cable from the right of the Airport card. Caution: both of these connections are very small. When re-assembling unit after repair, you may want to remove the two screws holding the airport card to the assembly and lift the card up and out to re-attach the cables.

Remove the two silver Phillips screws from the corners of the wireless interface board.

Grasp the board at the front and back, and lift up on the front until the board pulls free of its connector.
