A housing includes a cover, a plurality of foot pads and a plurality of couplers. Each of the plurality of foot pads is fixed on a corresponding one of the couplers and each of the couplers is pivotable about the cover. The cover defines a plurality of first receiving portions and a plurality of second receiving portions for receiving the plurality of couplers and the plurality of foot pads. Each of the plurality of foot pads and each of the plurality of couplers rotates relative to the cover to selectively receive the foot pad and the coupler in the first receiving portion and in the second receiving portion, so as to suspend the housing from a wall and to place the housing on a supporting surface.
