     2. Description of the Prior Art 
     Due to the improvement of information technology and the popularity of internet, the application of servers is more and more common. At present, the structure of a server commonly includes pluralities of circuit boards installed in a casing, wherein several kinds of electronic components are installed on the circuit boards. 
     However, it is unavoidable that some electronic components might break down or need upgrade after a period of time of use. When this happens, the users usually have to take apart the casing to replace the electronic components. At present, the procedure for replacing the electronic components commonly includes: taking apart the casing, replacing the broken or upgradeable electronic components and reassembling the casing. However, the replacement procedure costs much time, resulting in the inconvenience for the users. 
     It would, therefore, be desirable to redesign the casing which makes it easier and faster to replace the electronic components.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. 
     Please refer to  FIG. 1  and  FIG. 2  for an explosive view and an assembly drawing of a server of the first embodiment respectively. There is a server  1 , including a casing  11  and a power supply unit  13  which provides the server  1  with the power needed, wherein the casing  11  includes a casing body  111  and a carrier mechanism  112 . The casing body  111  has an internal space  1110 , and the carrier mechanism  112  is disposed in the internal space  1110 . Moreover, the carrier mechanism  112  includes a carrier unit  1121  and a fastening unit  1122 , which is disposed at the terminal of the carrier unit  1121 . A circuit board  12  is disposed on the carrier unit  1121 , wherein pluralities of electronic components are installed on the circuit board  12 , such as a memory  123 . There are heat sinks  122  disposed on some of the electronic components to increase the cooling effect. Besides, on both sides of the top surface of the fastening unit  1122  are pivoted two handles  1123  fastened by rotary screws  1124  respectively, wherein each one of the handles  1123  includes a transverse side plate  1123   a  and a longitudinal side plate  1123   b . The transverse side plate  1123   a  is pivoted on the top surface of the fastening unit  1122 , and the longitudinal side plate  1123   b  has a screw  1125 , which can be locked with the pinhole  1111  of the casing body  111 . 
     Please refer to  FIG. 1  again. A fan assembly  1126  is disposed inside the fastening unit  1122 , wherein the fan assembly  1126  includes three fans, which are drawing fans, to diffuse the heat inside the server  1 . In addition, an air guide hood  121  is installed on the circuit board  12 , wherein the air guide hood  121  and two fans of the fan assembly  1126  are in the corresponding positions. That is to say, the air guide hood  121  is disposed in the vent of the two fans. 
     What follows is the process of how the carrier mechanism  112  is taken apart from the casing body  111 . Please refer to  FIG. 2  and  FIG. 3A . First, the users loosen the screws  1125  to separate the screws  1125  and the pinholes  1111  of the casing body  111 . Then, the users pivot the rotary screws  1124  to turn the handles  1123  for some angles. Next, please refer to  FIG. 3B . The users can hold the handles  1123  and slide the whole carrier mechanism  112  backward, so as to pull the carrier unit  1121  of the carrier mechanism  112  out of the internal space  1110  of the casing body  111 . Afterward, the users can replace the electronic components on the circuit board  12 . After the replacement is done, the users can push the carrier unit  1121  back into the internal space  1110  and then lock the screws  1125  to the pinholes  1111  of the casing body  111 . 
     Several points for attention, there are two said handles  1123  in the present embodiment, yet those skilled in the art can also install only one said handle  1123  depending on their needs. Moreover, there is one said screw  1125  installed on each one of the handles  1123  of the embodiment, yet the number of the screw  1125  is not a limitation of the invention. Those skilled in the art can install more than one said screw  1125  on each one of the handles  1123 . Besides the fastening unit  1125 , those skilled in the art can still lock the handles  1123  to the casing body  111  by means of other fastening elements (such as a buckle unit). 
     In summary, the present invention can shorten the time spending on replacing the electronic components by using the casing used for electronic device so as to facilitate the users. Moreover, when manufacturing the servers, the manufacturer can save the cost by using the present casing. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
