A portable device having improved configurability and adaptability. The portable device has a case or chassis that can be placed in either an open or closed position, to thereby allow for insertion and removal of other devices within the portable device. When increased functionality is required or desired, the device's case is expanded by placing it in an open position, to allow additional devices to be operated in conjunction with the portable device. These devices can provide various types of electronic or computer operations, such as electronic adapters or media drives, as well as mechanical operations such as air movement with one or more additional fans or other types of heat sink. When decreased functionality is required or desired, such as to reduce the overall size and weight of the portable device, the device's case is contracted by placing it in a closed position. This allows on-demand expansion and contraction capability for the portable device. The expandable case provides dual functionality by also providing improved cooling for the portable device when in an open position.
