A parallel-plugged planar sandwich arrangement for a computer system includes a first printed circuit board having a first electrical connector on a surface thereof, and a second printed circuit board having a second electrical connector on a surface thereof. The second electrical connector is electrically mated to the first electrical connector, to electrically couple the first printed circuit board to the second printed circuit board. A stiffener panel is disposed between the first printed circuit board and the second printed circuit board. A disengagement mechanism is attached to the panel and includes a cam assembly that has a cam rotatable about an axis of rotation, a cam pin projecting out from opposite sides of the cam and being coaxial with the axis of rotation, and a torsional helical spring disposed around the cam pin for automatically rotating the cam in a first direction. A handle is attached to the cam. When the handle is pulled, the cam is rotated in a second direction opposite to the first direction so that the cam is caused to push against the first printed circuit board, thereby removing the first electrical connector from engagement with the second electrical connector while moving the first printed circuit board in a direction away from the second printed circuit board.
