SUMMARY OF THE INVENTION 
According to an aspect of the invention, an enclosure of a computer 
includes a U-shaped frame consisting essentially of a front panel, a rear 
panel and a bottom panel therebetween, commonly defining therein a 
rectangular parallelepiped space for receiving therein the components such 
as the mother board, the drive and the power supply, etc. Two side panels 
are attached to the frame. A top cover is slid unto the top of the frame 
with a locking button for releasably securing the top cover with regard to 
the frame, thereby allowing easy inspection and repair of the defective 
internal components. The enclosure further includes a securement plate 
with a plurality of grounding fingers thereon for retaining the switch 
power supply in position. A number of grounding fingers are provided on 
the top edge of the rear panel of the frame corresponding to the fingers 
of the securement plate, thereby providing the power supply with superior 
grounding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
References will now be in detail to the preferred embodiments of the 
invention. While the present invention has been described in with 
reference to the specific embodiments, the description is illustrative of 
the invention and is not to be construed as limiting the invention. 
Various modifications to the present invention can be made to the 
preferred embodiments by those skilled in the art without departing from 
the true spirit and scope of the invention as defined by appended claims. 
It will be noted here that for a better understanding, most of like 
components are designated by like reference numerals throughout the 
various figures in the embodiments. Attention is directed to FIGS. 1-3 
wherein an enclosure 10 of a computer includes a U-shaped frame 12 
consisting essentially of a front panel 14, an opposite rear panel 16 and 
a bottom panel 18 therebetween. Two reinforcement bars 20 are fastened 
between the top portions of the front panel 14 and the rear panel 16. A 
compressor holder 22 is positioned under the frame 12 for enclosing a 
compressor (not shown) therein. 
Adjacent to the front panel 14, a drive cage 24 for receiving the CD-ROM 
and the associated drive box 26 for receiving floppy drive is fastened to 
the frame 12 through binding to the reinforcement bars 20. Similarly, a 
power supply bracket 28 is secured to the frame 12 through binding to the 
reinforcement bars 20 adjacent to the rear panel 16. 
Referring to FIGS. 1-3, two side panels 30 are respectively mounted to two 
sides of the frame 12 in a back-to-front direction wherein the front edge 
32 of the side panel 30 can be engaged with the side edge 34 of the front 
panel 14, and the hooks 36 on the rear edge 37 of the side panel 30 may be 
respectively latchably received within the locking slots 38 in the rear 
panel 16. 
A top cover 40 can be slid along the top of the reinforcement bars 20 in a 
back-to-front direction and locked with the front panel 14 by means of the 
locking device 42 adjacent the front edge section 44 thereof. A locking 
slot 46 adjacent the rear edge 47 of the top cover 40 also receiveably 
engages the projection 48 rearward extending from the top edge 49 of the 
rear panel 16, whereby a hanging lock 53 can lock such projection 48 by 
extending through the hole 51 thereof (FIGS. 6 and 7) for avoidance of 
release of the projection 48 from the locking slot 46. Under this 
situation, the top cover 40 can be securely fixed to the frame 12. 
Two features are provided in the invention. The first one is regarding the 
structure for combining the top cover 40 and the front panel 14. Also 
referring to FIGS. 1-5, 8 and 9, the front edge section 44 of the top 
cover 40 around the region of the cross-section line IX (FIG. 1) forms a 
receiving slot 50 (FIG. 9) whereby the flange 52 on the top edge of the 
front panel 14 may be embedded therein for preventing the top cover 40 
from upward or forward moving. Differently, referring to FIG. 8, the front 
edge section 44 of the top cover 40 around the region of the cross-section 
line VIII (FIG. 1) forms a locking device 42 thereabouts. Such locking 
device 42 includes a resilient lever 54 with a locking press button 56 
exposed within an opening 58 formed in the top cover 40 and further with a 
latching lance 60 at the front end for latchable engagement with an 
engagement tag 62 formed on the flange 52 of the front panel 14. 
Therefore, when assembled, the top cover 40 is latchably secured to the 
front panel 14 by means of engagement of the latching lance 60 with the 
engagement tag 62 of the front panel 14. Oppositely, when disassembled, 
the press button 56 of the top cover 40 is forcibly moved downward to 
disengage the latching lance 60 from the engagement tag 62 of the front 
panel 14, thereby allowing the top cover 40 to move rearward. 
Referring to FIGS. 2, 6, 7 and 7(A), the second feature of the invention is 
regarding installation of the power supply 64. The power supply bracket 28 
provides the space for receiving therein the power supply 64 wherein the 
power supply 64 is inserted into such space in generally a front-to-back 
direction with a slightly slanted angle. First, the locking hooks 66, 
which are positioned around the edge 68 of the base plate 70 of the 
bracket 28, can be received within the elongated aperture 72 formed on the 
flange 74 of the power supply 64. Successively, the power supply 64 moves 
rearward to have the hooks 66 of the bracket 28 properly and lock the 
flange 74 of the power supply 64 in position. Finally, a power supply 
securement plate 76 is attached to the bracket 28 by means of engagement 
of the latching hooks 80 thereof within the latching slot 82 in vertical 
wall 83 of the bracket 28, whereby fingers 78 of the securement plate 76 
may press against the back of the power supply 64 for preventing forward 
movement of the power supply 64, thereby securing the power supply 64 in 
space defined by the bracket 28. It is noted that similar to the 
securement plate 76, the rear panel 16 includes fingers 84 for cooperation 
with the fingers 78 of the securement plate 76 for grounding and retaining 
the power supply 64 therebetween. 
The invention provides a novel structure and the corresponding assembling 
method to form an enclosure, for receiving the components therein, without 
screwing or other odd assembling procedure, thus saving time and cost 
during manufacturing. 
While the present invention has been described with reference to specific 
embodiments, the description is illustrative of the invention and is not 
to be construed as limiting the invention. Various modifications to the 
present invention can be made to the preferred embodiments by those 
skilled in the art without departing from the true spirit and scope of the 
invention as defined by the appended claims. 
Therefore, person of ordinary skill in this field are to understand that 
all such equivalent structures are to be included within the scope of the 
following claims.
