A panel member attaches to a frame that supports electronic circuitry. The panel member includes a mounting portion configured to mount to the frame, and a face portion coupled to the mounting portion. The face portion defines a plane and multiple openings within the plane. The panel member further includes multiple brimmed portions coupled to the face portion. Each brimmed portion (i) extends around an opening defined by the face portion and (ii) projects from that opening in a direction which is away from the plane. The use of such a panel member provides improved airflow and stagnation pressure as well as robust electromagnetic interference protection.

A heat sink attachment mechanism includes a fastener having an associated compressible member. The fastener defines a flange that, as the fastener secures a heat sink to a circuit board component, is configured to contact a circuit board surface associated with the circuit board component. Contact between the flange and the circuit board minimizes the travel of the fastener relative to the circuit board component and limits the stress generated on the circuit board component or on the solder balls of a ball grid array associated with the circuit boards component by the heat sink. Also, as the fastener secures the heat sink to the circuit board component, the fastener compresses the compressible member against the heat sink, thereby causing the compressible member to expand. Expansion of the compressible member allows the compressible member to absorb changes in the stress applied by the fastener to the heat sink and circuit board component over time.

An apparatus for mounting computer peripheral equipment, such as disk drives or CD ROMs, comprises a drive cage and rails. The drive cage, a part of a computer chassis, defines several bays for receiving disk drives or CD ROMs therein. The drive cage has side walls forming bends whereby each pair of bends defines a receiving channel in each bay, and spring tabs project into each bay. Two rails each having a leading end and spring fingers are attached to sides of the CD ROM for slidably mounting in the corresponding bay of the drive cage. The leading end of the rail facilitates alignment the receiving channel. The spring fingers abut against with the bend of the channel to prevent clearance from forming between the bend and the rail. When the CD ROM is fully inserted into the bay, the spring tabs are attached to the rail thereby providing good grounding and easy installation capabilities.

A circuit board assembly includes a motherboard defining a motherboard plane, and a daughter board defining a daughter board plane which is substantially parallel to the motherboard plane. The motherboard and the daughter board electrically connect to each other through a set of circuit board connectors. The circuit board assembly further includes a set of edge clips. Each edge clip extends outwardly from the daughter board along the daughter board plane and is configured to operate as a mounting platform through which to physically secure the daughter board to the motherboard.

An enclosure for a computer system comprises a base frame, a side panel and a bezel. The base frame comprises a top cover, a front panel, a rear panel, a base panel and a tray which forms an open box for receiving subsystems of the computer such as a mother board, a switching power supply, disk drives, a CD ROM etc. The side panel is pivotably mounted to the base frame for covering an opening of the box and is fixed to the rear panel by only one screw. The bezel has locating legs extending through alignment holes of the front panel and the side panel for mounting thereto.

A computer support device includes a housing and a keyboard drawer unit which is slidably supported on the inside of the housing for movement from a stored position to an extended position. The drawer unit contains a forward recessed section of sufficient size to accommodate a computer keyboard. The drawer unit also contains a rearward section which includes a recessed portion for storage as well as a switch assembly portion and a passageway for a keyboard power cord. The switch assembly portion includes a plurality of switches for control of the power supply to a computer and a host of peripheral devices. A power strip which includes devices for protection against electrical disturbances is connected to the drawer unit's switch assembly by a flexible power cord.
