An appliance such as a personal computer includes a metal chassis which comprises a main chassis section and a subchassis hingedly connected to the main chassis section for rotation about a horizontal axis between folded-in and folded-out positions. The subchassis carries operational components such as a power supply and a drive, and the main chassis section carries an operational component such as a motherboard. When the subchassis is in its folded-in position it overlies the motherboard and blocks access thereto, and when in its folded-out position the subchassis provides access to the motherboard. In its folded-in position the subchassis sits upon horizontal edges of the main chassis section.

Appliance chassis having hingedly mounted section

An appliance such as a personal computer includes a metal chassis which has a first section, and a second section mounted on the first section. The first chassis section forms a first space in which a motherboard is mounted. The second chassis section forms a second space in which a disk drive is mounted. The second chassis section defines a shield resisting the passage of electromagnetic waves between the first and second spaces to isolate the motherboard from a disk opening for the disk drive thereof.

Appliance having EMI shielding

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 fingers with hemispherical domes formed therein is then fitted and secured to the base such that the lateral edges of the fingers 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. A front panel having a front EMI shield is then mounted and secured to the top cover. 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 fingers formed in the rear EMI shield, the top cover assembly resting upon on the domes of the base EMI shield.
