Brand new Apple service spare complete bottom case for 1GHz & 1.25GHz models of 15" Aluminium PowerBook G4 (A1046). This unit comprises the aluminium shell, the lid catch and button, rib-cage, battery release catch and Airport cage. It does not include the Airport antenna cable. Although this complete part is not suitable for the 1.33GHz and Bluetooth 1.1 version of the 1.5GHz PowerBook, it is only the rib-cage that differs and the aluminium shell itself is the same part. The rib-cage can be easily removed via cross-head screws.
