[0048] FIG. 4A is a schematic diagram of the computer case 100 of
FIG. 2A whose motherboard extension stand 3 is located at a first
position with fans 71 and a water cooling kit 73 installed thereon.
FIG. 4B is a schematic diagram of the computer case 100 of FIG. 4A
viewed from another view-angle. Refer to FIG. 4A and FIG. 4B. If
the user has a requirement for dissipating the heat, the user may
install fans 71 and a water cooling kit 73 on the motherboard
extension stand 3 at the first position, such that the fans 71 and
the water cooling kit 73 are installed within the first space 15
and the second space 16. Besides, if the user has the requirements
for installing a hard disc and dissipating the heat, the user may
install the hard disc group 82 as shown in FIG. 3 on the bottom

[0049] FIG. 5A is an explosion diagram of a motherboard extension
stand 3 of a computer case 100 at a second position viewed from a
view-angle according to another embodiment of the invention. FIG.
5B is an assembly diagram of the computer case 100 of FIG. 5A. FIG.
5C is an explosion diagram of the computer case 100 of FIG. 5A
viewed from another view-angle. FIG. 5D is an assembly diagram of
the computer case 100 of FIG. 5C.
[0050] Refer to FIG. 5A, FIG. 5B, FIG. 5C and FIG. 5D which clearly
illustrate how the motherboard extension stand 3 at the second
position is connected to the motherboard stand 2. When the
motherboard extension stand 3 is switched to the second position
from the first position, the user may detach the motherboard
extension stand 3 from the motherboard stand 2 by removing the
fixing element 4 (such as a screw). Then, the motherboard extension
stand 3 is flipped upside down for 180.degree.. As indicated in
FIG. 5A and FIG. 5C, the motherboard extension stand 3 may include
a protrusion portion 33, which is protruded towards the negative Z
axis from the extension stand body 31 and is located on one side of
the extension stand body 31 facing the negative Y axis. The
computer case 100 includes an engaging portion 5 corresponding to
the protrusion portion 33, such as a recess corresponding to the
shape of the protrusion portion 33. Illustratively but not
restrictively, the engaging portion 5 may be disposed on the
horizontal portion 181 of the shielding plate 18, but the invention
is not limited thereto. For example, the engaging portion 5 may
selectively be disposed on other structure of the computer case 100
not mentioned above, After the motherboard extension stand 3 is
flipped upside down for 180.degree., the protrusion portion 33
which originally faces the top plate 13 will change to face the
bottom plate 14, and the second surface 32S2 of the second lapped
portion 32 of the motherboard extension stand 3 faces the lapped
surface 22S of the first lapped portion 22 of the motherboard stand
2. At this time, the user may lean the second surface 32S2 on the
lapped surface 22S and couple the second lapped portion 32 and the
first lapped portion 22 with the fixing element 4, and the
protrusion portion 33 may be engaged in the engaging portion 5.
Thus, the motherboard extension stand 3 is disposed at the second
position, and the second surface 32S2 of the second lapped portion
32 of the motherboard extension stand 3 overlaps the lapped surface
22S of the first lapped portion 22 of the motherboard stand 2.
[0051] FIG. 6A is a schematic diagram of the computer case 100 of
FIG. 5A whose motherboard extension stand 3 is located at a second
position with fans 72 installed thereon. FIG. 6B is a schematic
diagram of the computer case 100 of FIG. 6A viewed from another
view-angle. Refer to FIG. 6A and FIG. 6B. If the user has a
requirement for dissipating the heat, one or more than one fan 72,
such as but not limited to a 120 mm fan, may be disposed on the
motherboard extension stand 3 at the second position. As indicated
in FIG. 6B, the fans 72 are installed within the second sub-space
162 to blow an airflow towards the heating elements disposed on the
motherboard 6 (such as the central processing unit, graphics
processor, and memory) to enhance the convection around the
motherboard 6, such that the heat flow generated by the heating
elements may be dissipated via the fans 71 disposed on the rear
plate 12 and the top plate 13 to quickly dissipate the heat.
[0052] Besides, if the user has the requirements for installing a
hard disc and dissipating the heat, the user may install the hard
disc group 82 as shown in FIG. 3 on the bottom plate 14 within the
first space 15. Referring to FIG. 7, a schematic diagram of the
computer case 100 of FIG. 5A whose motherboard extension stand 3 at
a second position with hard discs 83 installed thereon is shown.
The user may install one or more than one hard disc 83 on the
motherboard extension stand 3 at the second position. The hard
discs 83 are disposed within the first sub-space 161, such that the
existing space within the computer case 100 may be effectively
utilized, To put it in greater details, the motherboard extension
stand 3 further includes an installation stand 84 disposed within
the first sub-space 161 and parallel to the top plate 13 and the
bottom plate 14. The hard discs 83 may be installed on the
installation stand 84. In the present embodiment, five installation
stands 84 are arranged to carry five hard discs 83. In the present
embodiment, the fans 71 and the water cooling kit 73 are installed
on the front plate 11, and the fans 71 and the water cooling kit 73
are installed within the first space 15 and the first sub-space 161
of the second space 16, but the present invention is not limited
thereto. Thus, since the airflow may enter the computer case 100
from the front plate 11, the air pressure between the front plate
11 and the motherboard extension stand 3 is increased, and the
airflow may be accelerated to quickly dissipate the heat.
[0053] Referring to FIG. 8, an explosion diagram of a computer case
100 in which two sides of the frame 1 are covered with glass covers
according to an embodiment of the invention is shown. After the
user completes the installation of the internal electronic elements
(such as the motherboard, the graphics card, the power) and the
peripheral devices (such as the hard disc and the fan) of the
computer case 100, the glass covers 9 may be disposed on the left
side and the right side of the frame 1 of the computer case 100 to
be adjacent to the front plate 11, the rear plate 12, the top plate
13 and the bottom plate 14. The glass covers 9 reveal the internal
view of the computer case 100 and produce a unique assembly style
of professional players.
[0054] According to the computer case of the invention, by changing
the assembly position of the motherboard extension stand, the user
may install necessary peripheral devices on the motherboard
extension stand without using additional fixing stands.
[0055] Besides, when the motherboard extension stand is located at
different assembly positions (such as the first position and the
second position), the motherboard extension stand may be used for
carrying several peripheral devices. In some embodiments, the
motherboard extension stand may be used for carrying not only the
hard disc but also the heat-dissipation device. Or, the motherboard
extension stand may be used for carrying both of the hard disc and
the heat-dissipation device. Therefore, the computer case of the
invention may meet the user's various requirements.
[0056] While the invention has been described by way of example and
in terms of the preferred embodiment(s), it is to be understood
that the invention is not limited thereto. On the contrary, it is
intended to cover various modifications and similar arrangements
and procedures, and the scope of the appended claims therefore
should be accorded the broadest interpretation so as to encompass
all such modifications and similar arrangements and procedures.
