BACKGROUND 
   1. Field of the Invention 
   The present invention relates to computer cases, and more particularly to a computer case with locking side panel and bezel. 
   2. Description of Related Art 
   Nowadays, computers have become increasingly popular for general use, which make it more and more important to prevent expensive components such as CPUs, hard disk drives or memory modules in the computer case from being stolen, so that locking computer cases have appeared. 
   Ordinarily, access to the inside of a computer case is through a side panel or a top panel. A lock is connected between the chassis and the side panel or top panel to prevent the computer case from being opened by unauthorized persons. However, control of access through a front bezel of the computer case is often neglected, so that the front bezel may be dismantled. 
   What is desired, therefore, is a computer case with locking side panel and bezel thereof. 
   SUMMARY 
   An exemplary computer case includes a chassis, a bezel, and a spring-loaded first locking member. The chassis includes a side panel and a front wall. The side panel can be disassembled from the chassis and includes an urging piece extending therefrom. The bezel is mounted to the front wall and includes at least one claw extending therefrom. The first locking member is slidably mounted to the front wall and can be urged by the urging piece of the side panel. The first locking member includes at least one hooking part corresponding to the at least one claw of the bezel. When the side panel is assembled to the chassis, the first locking member is urged by the urging piece of the side panel to slide relative to the front wall to make the at least one hooking part thereof be caught by the at least one claw of the bezel, and when the side panel is disassembled from the chassis, the urging piece of the side panel disengages from the first locking member, the first locking member restoringly slides to disengage the at least one hooking part thereof from the at least one claw of the bezel. 
   Other advantages and novel features will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

   Referring also to  FIG. 8 , the second locking member  50  is an elongated piece. A locking piece  51  with a locking hole  52  defined therein extends from a rear end of the second locking member  50 . Three sliding slots  53  corresponding to the three hooks  12  of the top wall  11  of the chassis  10  are defined near an upper edge of the second locking member  50 . A guiding slot  54  communicating with each sliding slot  53  is vertically defined at the upper edge of the second locking member  50 . A hook  55  extends from an inner side of the middle portion of the second locking member  50 , and an orifice  56  is defined near the hook  55 . Four square orifices  57  corresponding to the four rectangular orifices  15  are defined near a lower edge of the second locking member  50 . 
   Referring also to  FIGS. 9 to 12 , in assembly, the block  33  of the first locking member  30  is inserted through the square orifice  66  of the front wall  60  of the chassis  60 , the hooking piece  62  of the front wall  60  is inserted in the groove  31  of the first locking member  30 , and two screws  38  are respectively inserted through the sliding groove  346 ,  366  of the first locking member  30  and engaged in the screw holes  64  of the front wall  60 , so that the first locking member  30  is slidably mounted to the front wall  60  of the chassis  10 . Two opposite ends of a spring  39  respectively catch the hooking piece  32  of the first locking member  30  and the hooking piece  62  of the front wall  60 , so that the first locking member  30  is restricted by the spring  39  when sliding relative to the front wall  60 . The bezel  20  is mounted to the chassis  10 , and the claws  24  of the poles  22  of the bezel are received in the corresponding cavities  344 ,  346  of the first locking member  30  and catch the corresponding catching pieces  348 ,  368  in the cavities  344 ,  364 . 
   Referring back to  FIGS. 7 and 8 , the hook  14  of the bent part  13  of the chassis  10  is inserted through the orifice  56  of the second locking member  50 , the hooks  12  of the top wall  11  of the chassis  10  are guided by and slid along the corresponding guiding slots  54  of the second locking member  50  and then slidably engaged in the corresponding sliding slots  53 , the locking piece  51  of the second locking member  50  is inserted through the slot  72  of the rear wall  70  of the chassis  10  (see  FIGS. 2 and 3 ), and the second locking member  50  is supported on the carrying juts  16  of the bent part  13  of the chassis  10  and located between the carrying juts  16  and the chassis  10 , so that the second locking member  50  is slidably mounted to the chassis  10 , and at any position of the second locking member  50  in its sliding range, each square orifice  57  always overlaps the corresponding rectangular orifice  15  of the bent part  13 . To allow the bottom edge of the second locking member  50  to clear the carrying juts  16  in assembly when it is fit to the bent part  13 , a plurality of indentations  58  corresponding to the carrying juts  16  of the bent part  13  is defined in the lower edge of the second locking member  50 . Two opposite ends of a spring  59  respectively catch the hook  55  of the second locking member  50  and the hook  14  of the bent part  13  of the chassis  10 , so that the second locking member  50  is restricted by the spring  39  when sliding relative to the chassis  10 . The side panel  40  is mounted to the chassis  10 , and the hooks  44  of the side panel  40  are in turn inserted through the corresponding rectangular orifices  15  of the bent part  13  of the chassis  10  and the corresponding square orifices  57  of the second locking member  50 , thereby the urging piece  42  urges against the block  33  thereby sliding the first locking member  30  along its path. 
   In use, a lock (not shown) is used to lock the locking piece  51  of the second locking member  50 , and because of the force of the spring  59 , the hooks  44  of the side panel  40  catch a wall of the second locking member  50  bounding the square orifices  57  in a normal state, so that the side panel  40  can&#39;t be disassembled from the chassis  10 . Referring to  FIGS. 9 to 12 , in assembling the side panel  40  to the chassis  10 , the urging piece  42  of the side panel  40  pushes the block  33  of the first locking member  30 , thus urging the first locking member  30  to slide to a right side of front wall  60  of the chassis  10  and the spring  39  is stretched, so that the claws  24  of the bezel  20  may catch the corresponding catching pieces  348 ,  368  in the cavities  344 ,  346  of the first locking member  30 . Thus, locking the bezel to the chassis  10 . In disassembly, the lock is detached from the locking piece  51  of the second locking member  50 . The locking piece  51  is pushed to make the second locking member  50  slide forward until the hooks  44  of the side panel  40  disengage from the wall of the second locking member  50 . The hooks  44  of the side panel  40  are in turn drawn out from the corresponding square orifices  57  of the second locking member  50  and the corresponding rectangular orifices  15  of the bent part  13  of the chassis  10 , so that the side panel  40  can be disassembled from the chassis  10 . Thus, the urging piece  42  of the side panel  40  disengages from the block  33  of the first locking member  30 , the spring  39  is restored to drive the first locking member  30  to slide to a left side of front wall  60  of the chassis  10 , the claws  24  of the bezel  20  disengage from the corresponding catching pieces  348 ,  368  in the cavities  344 ,  346  of the first locking member  30 , so that the bezel  20  can be disassembled from the chassis  10 . 
   Thus, the wealth components in the chassis  10  are safeguarded by preventing unauthorized disassembly of both the side panel  40  and the bezel  20 . 
   It is believed that the present embodiment and its advantage will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being an exemplary embodiment of the invention.
