ABSTRACT:
A chassis of a device, for example an electronic device, includes a support unit made of plastic material which carries the components of the device, such as printed circuit boards, a data storage disk, a ventilator, and a loudspeaker. The components are held in place in corresponding recesses of the chassis by a form-locking connection with the plastic material. The components are carried by the chassis without requiring any fastening elements. For assembling the device, the components are inserted into the lower part of the chassis. Thereafter, the upper part is positioned on top of the lower part. The chassis can be enclosed in a metal enclosure. The chassis is preferably manufactured by a plastic molding process. Ventilation ducts can be provided in the plastic material to ensure cooling of the components.
