Abstract: A computing system is proposed for installation or retrofit in homes or offices. The system easily installs in wall structures without concern for interference with load bearing structures. In its varying embodiments the system provides for audio or video entertainment, security, remote monitoring, and all forms of communications and networking with other computing systems and appliances. The system exploits a menu-driven graphical user interface, a rigid framing mechanism and special ventilation techniques to achieve an unprecedented computing system for integral incorporation within a home and office.
