A PCI card is inserted through an I/O opening in a computer panel. On one edge of the card is a cover from one end of which projects a tab. A resilient gasket is attached to the panel to create a flexible EMC seal around the opening. Preferably the gasket is formed of tin-plated beryllium copper. The gasket has alternate staggered spring fingers oriented opposite to the direction of insertion of the PCI card. To retain the gasket the panel is formed with slots at either end and an outward struck projection at the middle. The gasket is formed with a tongue at either end to be inserted in one of the slots and a punched-out opening to receive the projection.

A structural foam, injection molded superstructure is attached to a motherboard by means of threaded inserts. The superstructure is formed with guide ways for CPU processor modules, and also for the edges of PCI cards. Features of the structure include cam levers on the CPU modules to install and extract the modules. A metal transverse vertical retaining bracket is attached to the superstructure to hold sides thereof parallel and prevent splaying of the free, open end of the superstructure upon extraction of CPU processor modules. The assembly provides stiffness to the motherboard.
