A chassis for a counter-top touch-screen interface terminal associated with a central processing unit has a lower housing and an upper housing. The upper housing engages and rests on the lower housing and includes a touch-screen for communicating information that is with the central processing unit, a customer display for displaying information that is communicated through the touch-screen, and a swipe reader for receiving a card having information usable by the central processing unit A socket pluggably receives a terminal cable for carrying power to the terminal and communicating signals with the central processing unit The socket is positioned within a recess of the upper housing From the chassis, a slide bar protrudes to slidably engage the upper housing with the lower housing. Also, a slide guide protrudes from the upper housing to restrict side translational movement of the upper housing relative to the lower housing. An adjustment bar from the upper housing selectively engages one of a plurality of adjustment detents in the lower housing as the upper housing engages and rests on the lower housing to provide one of a variety of selectable fixed viewing angles of the touch-screen.

A personal computer CPU chassis (10) is sealed from the emission of radio frequency (RF) through the expansion slots (24) in the rear panel (18). An expansion slot seal (37) is dimensioned to fit over the edges or strips (32-34) of the slots (24) and is held in place by a slot cover (26). The seal (37) has a flat portion (46) for direct contact with the strips (32-34) and an angled portion (48) for direct contact with the cover (26). The cover (26) is held in place by a screw (54) and a retaining device (60) which forces the cover (26) into the seal (37). Thus a metal-to-metal seal is formed around the expansion slots (24) to inhibit the emission of RF therefrom.

L-shaped flanges (20) are formed integrally with both edges of the base (12) on a computer chassis (10). U-shaped channels (26) are also formed integrally with both edges (21-22) of the cover (14) on the computer chassis (10). The cover (14) is installed over the base (12) by matching the U-shaped channels (26) with the L-shaped flanges (20) and sliding the cover (14) into position. The metal-to-metal contact all along the U-shaped channels (26) and the L-shaped flanges (20) helps retard the emission of radio frequency from the chassis (10).
