A mounting system for attaching a panel to a chassis includes a chassis having a top, a bottom and opposing sides. A guide portion is attached adjacent to the top of the chassis. A latch is movably mounted to the chassis adjacent to the guide portion. The guide portion engages the latch to limit the movement of the latch along a reference axis defined by the guide portion. A resilient member is connected between the latch and the chassis for biasing the latch to a static position. A panel is pivotally attached adjacent to the bottom of the chassis. The panel is engaged by the latch to retain the panel in a closed position. The latch is movable to a displaced position for releasing the panel to allow the panel to be moved to an open position. The panel can be accurately and consistently aligned and attached to the chassis of the computer system after each removal. Furthermore, the panel can be quickly and easily engaged and disengaged with minimal force without the use of tools or having to manipulate fasteners such as screws.
