Abstract

A modular computer chassis with passive backplane is provided for a personal computer system with a plurality of open-ended and vertically or horizontally interconnectable bays, or a single case with bays, for slidably receiving component trays each having a printed double sided bus direction adaptor board with a bus connector at one end and a female bus connector mounted to the top surface for attaching an expansion card parallel to the board. The end bus connector extends through the back wall of the tray to connect to a female bus connector on a passive backplane connector board attached to the back of the chassis. The adaptor board converts the established bus connection between the card and female bus connector 90 degrees to the bus connector at the rear of the tray. A front cover, or individual tray covers, cover the front of the chassis as a locking and security mechanism. The bays connect and hold standard off-the-shelf personal computer components, and additional bays may be added and connected to the system, or used at remote locations, by means of an external cable harness or cable connector which attaches to the backplane board.
