Control Panel/Frame Retaining Mechanism for Personal Computers

      Disclosed is a hardware implementation to provide a retention
mechanism for the control panel bezel assembly of a personal computer

(PC).  The mechanism is designed to improve assembly and
manufacturability.  The mechanism involves the use of projections
incorporated on each side of the control panel bezel assembly to
enable the bezel assembly to be held by the frame.

      Typically, a PC incorporates device units such as:  a) a
primary circuit board, also known as the mother board or planar board
to interpret input commands and to deliver output commands; b)
input/output (I/O) circuit boards, also known as feature cards or
option cards which allow the output of the planar board to be
transferred to an exterior user device; c) a direct access storage
device (DASD), also known as hardfiles or hard drives.  These device
units allow the user to store planar board output commands for future
use.  As PC functions increase, there has been an increase in DASD
options and tasks to be performed by the system unit.  This has
necessitated the need for a control panel modular envelope that would
integrate device configurations such as the following:

o   Light emitting diodes (LEDs) to inform the user of a certain task
    status performed by the user or mode.

o   On/Off switch assemblies to control the power to the system,
    DASD, and to the option and planar cards.

o   Speaker component mounted to the control panel in close proximity
    to LED's and switches.  The location is critical in order to
    reduce electro-magnetic interference (EMI).

o   Integration of a multi-purpose control panel that is easily
    removed and can be upgraded or replaced by the user or during
    manufacturing before a retainer and top cover is installed.

      In prior art, screws were used to position the various units in
place to the frame of the PC.  The concept described herein
