Personal Computer Mechanical Package

      Disclosed is an economical mechanical package for a personal
computer enclosure incorporating a number of features providing
flexibility, and manufacturability.  The Figures described below
illustrate a preferred sequence of assembly for a personal computer
using this enclosure.

      Fig. 1 is an exploded isometric view of base 10, planar
(system) board 11, a front multi-media control assembly 12, a rear
multi-media control assembly 13, and speaker assembly 14.
Multi-media features present in both front control assembly 12 and
rear control assembly 13 include volume and mute controls, together
with jacks for the attachment of cables from a microphone and from
earphones.

      Planar board 11 is located by a pin 15, extending upward from
base 10 through a hole 16, and is fastened in place by means of a
number of screws 17 engaging standoffs 18.  Each standoff 18 engages
a pair of slots in base 10, with additional slots being provided so
that the standoffs can be arranged to accommodate a number of
different types of planar boards.  Each multi-media control assembly
12 and 13 in fastened to base 10 by means of screws 19, and speaker
assembly 14 is held in place by a tab 20 engaging a slotted bracket
portion 21 of frame 10 and by a screw 22 also engaging frame 10.

      Fig. 2 is an isometric view of a system assembly 24 including
the components and assemblies described above in reference to Fig. 1,
a power supply 25, a support bracket 26, and an optional fan assembly
27,  in an exploded relationship with an I/O card cage assembly 28, a
front PCMCIA socket assembly 29, and a rear PCMCIA socket assembly
30.  Support bracket 26 is fastened at the rear within base 10 by
means of a pair of screws 31 extending through holes 32 (shown in
Fig. 1) and at the front by a means of a pair of screws 33 extending
through holes 34 (also shown in Fig. 1).  Optional fan assembly 27
may be used, with suitable cooling slots in various external surfaces
of the system, to provide a segmented flow of cooling air, with air
being driven from front to rear on the left side of support bracket
26 by fan assembly 27 and on the right side of support bracket 26 by
a fan assembly (not shown) within power supply 25.

      Before card cage assembly 28 is attached to system assembly 24,
a decorative panel 36 is installed along the rear surfaces of this
cage assembly 28, with tabs (not shown) along a left edge of panel 36
engaging slots (not shown) in a left end bracket portion 37 of cage
assembly 28.  Panel 36 is pivoted into place in the direction of
arrow 38.  Card cage assembly 28 includes a riser card 40, having a
tab portion 42 extending downward to engage a card-edge connector 44
on planar board 11, as this assembly 28 is brought into place
straight downward onto base 10, with vertical card cage surfaces 46
sliding along mating surfaces of the base 10.  The system bus is
brought into the card cag...
