Abstract: A case for computing devices includes an interface which provides connection to a plurality of auxiliary hardware resources. The plurality of auxiliary hardware resources may be mounted in the case. The case may also include space to accommodate the computing device in the case frame. As computing demands increase for the computing device, the computing device may be connected to the case frame's interface, which via an electrical bus, connects the computing device to one or more of the auxiliary hardware resources in the case. In some embodiments, the auxiliary hardware resources may be accessed by the user on-demand. In some embodiments, a cooling fan may cool the ambient temperature of the case and/or individual auxiliary pieces of hardware.
