Abstract: A tool-less latch mechanism for attaching a panel to an enclosure for electronic equipment such as a computer. A lever is mounted to a first enclosure component at a pivot point and is operable to move in a pivot plane. A pawl extends from the lever substantially orthogonal to the pivot plane, and an arcuate slot is fixed on a second enclosure component. When the lever pivots from an open to a closed position, engagement of the pawl with a first surface of the slot causes relative movement between the enclosure components in a first longitudinal direction. When the lever pivots from the closed to the open position, engagement of the pawl with a second surface of the slot causes relative movement between the enclosure components in an opposite longitudinal direction.

Abstract: A circuit card retention device includes a longitudinal retention bar hinge-mounted to a support member of a computer enclosure or chassis. First and second hand-releasable lock members are attached to the retention bar at either end. Each lock member includes a flexible stop. When the retention bar is in a retaining position, the flexible stops engage a substantially rigid surface of the enclosure or chassis, keeping the bar in the retaining position. The flexible stops may be disengaged from the rigid surface by application of finger pressure, allowing the retention bar to pivot from the retaining position to an open position.

Abstract: A computer system comprises a chassis having a frontal mounting surface. The system also comprises a bezel-less drive cage coupled to the chassis and adapted to receive at least one frontally-exposed drive. The drive cage extends forward beyond the frontal mounting surface of the chassis.
