The MCE Optical Drive Enclosure for Unibody SuperDrive was designed specifically for use with the internal Apple SuperDrive that ships inside all MacBook Pro unibody and MacBook unibody systems. Installation of the SuperDrive into the MCE Optical Drive Enclosure is a breeze and takes about five minutes. Once inside, the drive is entirely enclosed. DVD and CD media is inserted through the front slot which is protected by a dust flap. The enclosure is silver in color to match the unibody MacBook Pro and it is completely bus-powered... making it 100% portable since no extra power supply is required. With your SuperDrive inside this enclosure you'll be able to use it anytime you want to for loading system software or applications, as well as burning, playing, or ripping CDs and DVDs! When finished, it is so slim and lightweight that it slips easily into your laptop bag, desk drawer, or on a shelf... until you need it again.
