The above described features and advantages of the present invention will become more apparent from the following description. Embodiments FIG. 2 is a schematic diagram of a computer system according to an embodiment of the present invention. Referring to FIG. 2, the computer system 2 of the present embodiment mainly includes a casing 21 and a power supply 22 disposed in the casing 210 and a circuit board 230 such as a mother board. . The casing 210 is composed of a front cover 212, a rear cover 214, a top plate 216, a bottom plate 21δ and two side plates 219. In order to facilitate the viewing of the internal components of the casing 21, the position is shown in FIG. The computer system 2 is only exemplified by the side plate 219. In the present embodiment, the front cover 212 corresponds to the rear cover 214, the top plate 216 corresponds to the bottom plate 218, and the top plate 216 and the bottom plate 218 are respectively joined to the two ends of the front cover 212 and the rear cover 214, and The side plate 219 is engaged with the front cover 212, the rear cover 214, the top plate 216, and the bottom plate 218. Further, the circuit board 230 is disposed adjacent to the rear cover 214. In particular, in order to enable the computer system 200 to have a better space utilization rate, the power supply 220 and the reading device 240, such as a hard disk or an optical disk drive, are assembled to the front cover 212. More specifically, in the present embodiment, the power supply 220 and the reading device 240 are respectively assembled to the front cover 1363950 0960175 24437 twf.doc/n plate 212 adjacent to the top plate 216 and adjacent to the bottom plate 218. That is, the power supply 220 is disposed adjacent to the top plate 216' and the reading position of the reading device 240 is adjacent to the bottom plate 218. Wherein, since the power supply 220 and the reading device 240 are also assembled to the front cover 212, when the computer system 200 is oriented toward the trend of compactness, the overall size of the casing 210 is reduced, the rear cover 214 and the power supply There is still a suitable space between the 220 or the reading device 240, and the standard size circuit board 230 or other large-sized circuit board 230 can still be disposed in the casing 210. That is, the user can flexibly select an appropriate circuit board 230 according to his use requirements, and can smoothly arrange it in the casing 210. In addition, in this embodiment, a power socket 250 ′ is disposed on a portion of the rear cover 214 adjacent to the top plate 216 , and a power cord 260 of the computer system 200 can be disposed on the power socket 250 and the power supply along the top plate 216 of the casing 210 . Between the devices 220 (ie, one end of the power line 260 is connected to the power supply 220' and the other end is extended to the power socket 250 along the top plate 216 of the casing 210). It is worth mentioning that, in this embodiment, since the top line of the power cord 26 〇疋 口 机 210 210 210 is not provided between the power socket 250 and the power supply for the crying 220, the power line 26 工作 in the working state It is not easy to generate electromagnetic interference (EMI) on the circuit board 230 disposed in the case 210, and the circuit board 230 can be in a normal working state. In addition, in order to enable the computer system of the embodiment 2〇〇 For example, a plurality of first openings 212a and a plurality of second openings 9 1363950 0960175 24437twf.doc/n 216a are respectively disposed on the front cover 212 and the top plate 216 of the casing 210. For example, the arrangement position of the second opening 216a corresponding to the reading device 24 is corresponding to the position of the power supply=220, and A first fan 222 of the power supply 22 is used to generate an air flow to remove the inside of the casing 21. In detail, the operation of the first fan 222 causes airflow from the first opening 212a into the casing 210' and sequentially flows out through the second opening 216a via the reading device 240 and the package source 220'. Outside the casing 210. In this way, the heat generated by the reading device 240 and the power supply 22 can be effectively removed by the airflow to the outside of the casing 21, and the temperature inside the casing 210 can be lowered. Of course, the heat generated by the heat generating component disposed in the casing 210 can also be removed to the outside of the casing 210 by the airflow. On the other hand, in this embodiment, a plurality of third openings 214a' may be disposed in the cover 21 of the casing 21, and at least one second fan 270 is disposed on the rear cover 214 (FIG. 2 shows two second fans). The second fan 27 is, for example, a system fan, and the second fan 27 is disposed, for example, corresponding to the arrangement position of the third openings 214a, so when the second fan 270 operates At the same time, another airflow flows out of the casing through the second openings 214a through the casing 210, thereby removing heat generated by the circuit board 23 or other heat generating components. 3A is a perspective view of a computer system according to another embodiment of the present invention, and FIG. 3B is an exploded view of the power supply bracket of FIG. 3A and the power supply and the casing, wherein FIG. 3B removes the front cover of the casing, One side plate and reading device. Referring to FIG. 3A and FIG. 3B simultaneously, the computer system 1363950 0960175 24437 tw doc/n system 300 of the embodiment further includes a power supply 2 bracket 280, and the power supply device is compared with the computer system 2 of the above embodiment. The 22G can be attached to the front cover 212 by a power supply bracket. In this embodiment, for example, a plurality of thin openings 219a are disposed in the side plate 219, and the arrangement positions of the openings (10) are, for example, the position source source 220 of the power supply 22 在 in the working position. The heat generated by the temperament θ + can be dissipated into the external environment via the plurality of fourth openings 219a on the side panel.
