A computer comprises a chassis having an inner surface and an outer surface and a processing device contained within the chassis. A portion of the chassis inner surface is positioned proximate to the processing device, and a sheet of thermally conductive interface material is positioned between and contacts the processing device and the inner surface portion to thermally couple the processing device to the chassis so that the heat generated by the processing device is delivered to the chassis. The outer surface of the chassis is configured, such as with fins, for dissipating heat from the chassis. A phase-change material is positioned on the inner surface of the chassis and absorbs heat to further assist the chassis in heat dissipation.
