Abstract: A foldable blank includes a substrate and a conducting layer. The substrate is folded so as to form a component housing. When the substrate is folded to form a housing, the conducting layer provides electrical shielding to devices situated within the housing. The housing has holes situated therein to accommodate air flow and external connections to devices located within the housing. The housing may be employed to envelop a chassis manufactured from expanded polypropylene.

Abstract: The housing assembly for holding device components comprises a housing and a chassis and can be integrally coupled to a standard piece of furniture. The housing may be in the form of a drawer which can be inserted and withdrawn from a standard unit of furniture such as a desk or cabinet. The drawer has perforations in its bottom and sides for air flow and is preferably made from a metal or metallic material but alternatively may be made from a non-metallic material which is lined with a metallic film. The chassis is made of plastic, preferably expanded polypropylene and may comprise two parts in which are secured equipment components. Projections extend from the sides of the chassis and extend to the drawer walls and thereby create air ducts through which air may flow to cool the components situated in the chassis. Plastic inserts may be placed in the air ducts created by the projections so as to direct the air flow within the assembly.
