If the Cube has an Airport card installed, it must be removed. This can be accomplished by disconnecting its antenna, and pulling gently on the clear plastic tab on its end. The bracket it is contained in must be unlatched from the frame and rotated out of the way to get to the two optical drive mounting screws beneath it.
