Apple has posted details on a new Power Mac G4 Power Supply Exchange Program, which “offers owners of Power Mac G4 (Mirrored Drive Doors) computers the option of reducing the operating acoustic level of their computers by exchanging their original power supplies and system fans for new, quieter versions.” The Power Supply Exchange Program kit is available at no charge, with a shipping and handling fee of US$19.95. The kit contains the following items: power supply (360 W); system fan; allen key (2.5 mm); installation instructions; and a prepaid return airbill and instructions for returning the original components to Apple. The program ends June 30, 2003.
