A modular enclosure for personal computer systems, and methods for assembly of an enclosure. The enclosure substantially comprises a base, a unitary internal frame, a front and a back panel, and a U-shaped top cover. Frame-mounting snaps and cruciform members located on forward and rear portions of the frame mate to complimentary receiving openings in the base. Front and rear panels are mounted to the base, frame, and top cover by a plurality of panel-mounting snaps and hooks. A base electromagnetic interference (EMI) shield at the periphery of the shield having a plurality of planar tabbed finges with hemispherical domes fommed therein is then fitted and secured to the base such that the lateral edges of the finges are recessed below a peripherally extending rim on the base. Thereafter, the internal frame is snapped into place upon the base, and a rear panel having an EMI shield fitted and secured to the base and frame by panel-mounting snaps and hooks. Subassemblies are then placed into the respective bays and secured via a plurality of subassembly retaining snaps and electrically interconnected via main and secondary cable bundles. A front panel having a front EMI shield is then mounted and secured to the top cover. One or more bezels are detachably mounted to the front panel via hooks and snaps to perrmt access to the subassembly devices frontally mounted in the bays of the built up base-frame assembly. The top cover assembly is then lowered onto the base frame assembly and slideably moved rearward until the rear edges of the top cover assembly contact a plurality of contact finges formed in the rear EMI shield, the top cover assembly resting upon on the domes of the base EMI shield. The top cover assembly is thereafter secured to the base-frame assembly by conventional thumbscrews.
