A rack adapted for receiving one or more components is disclosed. The rack includes a backplane, a pair of side panels extending from the backplane and internal support members on each side to receive and mechanically guide an initial alignment of components upon their initial insertion in the rack. A pair of male connectors mounted to the backplane is configured to mate with a corresponding pair of female connectors of each component to mechanically guide a final alignment of each component when the component is further inserted in the rack. Mechanical guidance may also be provided by, or supplemented with, a connection capable of providing liquid cooling to the rack. A system including the rack and the component inserted in the rack is also disclosed.
