A computer housing includes a frame and a face panel. The frame includes a plurality of pivotally interconnected frame panels such that the frame is convertible between an assembled state and a flattened state. In the assembled state, the frame panels form a rectangular frame for mounting electronic components, such as a motherboard, a disk drive and a hard disk. In the flattened state, the frame can be flattened out so that the frame panels lie in substantially the same plane, thereby reducing the space occupied by the frame.
