An assembly is disclosed which enables a printed circuit board (PCB) to be added to or removed from a computer system without deactivating other parts of the system. The assembly, which holds the PCB, translates lateral motion into vertical motion to enable lateral motion to be applied to derive the vertical motion needed to plug and unplug a PCB into and out of an expansion slot. This motion translation makes it possible to insert or remove a PCB via a rear, front, or side access portal of a housing rather than through the top of the housing. Thus, the assembly eliminates the need to remove the housing from a rack, or to remove a top from the housing, which in turn eliminates the need to shut down any other parts of the system. Thus, the assembly enables a PCB to be 'hot swapped' into and out of a computer system.

A computer system housing with a curved bezel that forms one or more sideways gap between a side of the computer housing chassis and the bezel attached to that side. Typically, the curved bezel is attached to the front of the chassis with each sideways gap extending perpendicularly from the front of the chassis to a predetermined width and stretching to predetermined length along the front of the chassis. The sideways gaps facilitate increased air inlet from the sides and allow efficient cooling of various system components that are mounted on the chassis and housed within the housing. One or more cooling fans may be mounted at different locations within the housing to optimize air circulation and, hence, cooling within the housing. The chassis may be partitioned into two separate sub-chassis for proper positioning of the cooling fans as well as to accommodate changes in computer system configurations with minimized retooling of the chassis.

Computer system housing and configuration

A stiffener for a printed circuit board where the stiffener is placed between the printed circuit board and a wall of the metal chassis in a computer system housing. The loaded printed circuit board may first be mounted on the stiffener, which, in turn, may then be mounted on the appropriate wall of the chassis along with the circuit board. Alternately, the stiffener may first be mounted on the appropriate chassis wall, and the circuit board may then be mounted on the stiffener. Additional circuit components may then be added onto the circuit board. The lies between the circuit board and the wall of the chassis on which the circuit board is being mounted. The back plane support provided by the stiffener may reduce damage to the conducting paths of the printed circuit board due to pressures exerted during component mounting, manufacture, transportation, etc. Additionally, a circuit board carrying densely populated electronic components may be easily mounted on or removed from the chassis without damage. Adequate board-to-chassis grounding may also be accomplished through the sheet metal stiffener frame. Horizontal and vertical struts in the stiffener frame may provide additional stiffness and rigidity in the vicinity of the high density connectors on the circuit board. Besides increased stability, unusually tight tolerances on the flatness of the circuit board surface near high density connectors may be achieved with the support provided by the stiffener.

The present invention is a computer housing with a low noise cooling system. The computer housing is comprised of two principal members, a cover and a base. Both a left surface and a right surface of the cover are perforated with vents to allowing the passage of air through the housing. The base additionally incorporates two air intake holes with a power source for the computer disposed over these air intake holes. The passage of air through the housing is facilitated through the use of three fans. These three fans are attached directly to the power source, and each of these fans operates at a different fan speed. The fan speeds are additionally adjusted in response to the outside ambient temperature. In operation, air enters the computer housing of the present invention through the vent array on the left surface of the cover, and the air intake holes in the base. The air is then channeled under the power source, dissipating the heat generated by the power source, blown across the components in the housing, and passed out of the housing through the vent array disposed on the left surface of the cover. The flow of air from one of the fans is advantageously deflected and channeled with a deflector.
