Abstract
A computer chassis has a cotton side wall upon which a two-section support plate structure is mounted. Each of the two support plate sections has, along a side edge periphery thereof, an upturned TEM shielding lip portion. The plate sections are supportingly securable to the underside of a printed circuit board, such as the computer motherboard, and are slidably adjustable relative to the underlying bottom chassis side wall to selectively adjust the overall size of the support plate structure so that different sizes of printed circuit boards may be alternatively secured thereto while maintaining proper spacing between the TEM shielding lip portions and adjacent side edge portions of the supported circuit board.
