Abstract: The present invention provides an enclosure that stores accessories for computer-related devices in zero unit space. The enclosure comprises a frame with horizontal and vertical members coupled with frame tracks. The frame supports computer-related devices, such as server blades, in a rack unit space. The computer-related devices, being supplied by different vendors, have varying sizes, shapes, and attachment requirements. The frame tracks are adapted to attach accessories, such as a power source, a cooling device, or a wire guide, in a zero rack unit space. The frame is configured according to the EIA-310-D standard. The accessories and computer-related devices are mounted to the frame and the frame tracks using tool-less adapters.
