The invention is directed towards assemblies of electrical or electronic circuit boards. More specifically, the present invention relates to an assembly for housing multiple computer circuit boards. The assembly include a housing that has several railing coupled to the housing. A connector is structurally and electrically coupled to the railings for hanging the computer circuit boards. Structural coupling between the connector and the railing is accomplished by placing the connector in contact with the railing in a file hanging method. This contact also creates an electrical coupling and establishes an electrical connection between the connector and the railing.
