     The present disclosure relates to a computer enclosure which can be conveniently assembled and disassembled. 
     2. Description of Related Art 
     Computer enclosures often include a base and a mounting bracket installed thereon. The base includes a bottom panel and a motherboard installed on the bottom panel. The mounting bracket includes a mounting plate and a plurality of expansion cards mounted thereon. The expansion cards are received in the corresponding slots of the motherboard, and the mounting plate of the mounting bracket is usually mounted on the base with many fasteners, thereby securing the mounting bracket to the base to complete assembly of the computer enclosure. This process, for both assembly and disassembly, is laborious, time-consuming, and inconvenient. 
     What is needed, therefore, is a computer enclosure which can be conveniently assembled and disassembled.

     The locating member  353  includes a bottom plate  3531 , two side plates  3533  extending substantially perpendicular from two opposite edges of the bottom plate  3531 , and two angled plates  3535  extending substantially perpendicular from the other two opposite edges of the bottom plate  3513 . An engaging portion  3537  is defined in a connection between the one of the angled plates  3535  and the bottom plate  3513 , and the engaging portion  3537  defines a triangular opening. A resilient piece  3539  protrudes from the bottom plate  3531  adjacent to the engaging portion  3537 . A round hole  3532  and a groove  3534  are correspondingly defined in the bottom plate  3531  adjacent to the resilient piece  3539 . 
     The sliding member  355  includes a rectangular sliding wall  3551  and a sawtooth-shaped operating portion  3553  on one side thereof, and a connecting member  3555  extending perpendicularly from the other side. A securing portion  3557  protrudes from a top side of the connecting member  3555 , received in the round hole  3532  of the locating member  353 . A resilient component  3559  is mounted to the connecting member  3555  adjacent to the securing portion  3557 . A top angled portion of the resilient component  3559  is seated and secured in the groove  3534  of the locating member  353 , and a free end of the resilient component  3559  pivotally extends through the pivot hole  3517  of the assembly member  351 . 
     Referring from  FIGS. 4 and 6 , in assembly, the locating member  353  is installed in the assembly member  351 , the engaging portion  3537  of the locating member  353  aligns with the mounting hole of the collar  3519  of the assembly member  351 . The two opposite edges of the bottom plate  3531  abut the corresponding locating piece  3516 , and the outer surfaces of the two side plates  3533  of the locating member  353  abut the inner surfaces of the corresponding blocking pieces  3518 . The sliding member  355  is installed in the assembly member  351 , the securing portion  3557  of the sliding member  355  is secured in the round hole  3532  of the locating member  353 . The top angled portion of the resilient component  3559  runs through and is secured in the groove  3534  of the locating member  353 , and the free end of the resilient component  3559  pivotally extends through the pivot hole  3517  of the assembly member  351 . Two opposite edges of the sliding wall  3551  of the sliding member  355  abut the inner surfaces of the corresponding vertical walls of the assembly member  351 , and assembly of the mounting mechanism  35  is complete. The mounting mechanism  35  is mounted to the mounting plate  31 , and the operating portion  3553  of the mounting mechanism  35  is exposed to the opening  311 . The mounting bracket  30  is impelled towards the motherboard  15  of the base  10 , and the expansion cards  33  are aligned with the corresponding slots  153  of the motherboard  15 . The guide portion  1517  of the mounting pole  151  of the motherboard  15  is received in the mounting hole of the collar  3519  of the mounting mechanism  35 . The guide portion  1517  presses against the resilient piece  3539  of the locating member  353  and the two inner edges of the engaging portion  3537  to move the sliding member  355  and the locating member  353  away from the mounting pole  151  perpendicular to the mounting pole  151 , whereupon the resilient component  3559  elastically deforms. When the connecting portion  1515  of the mounting pole  151  aligns with the engaging portion  3537 , the resilient component  3551  returns to its original state, and the two inner edges of the engaging portion  3537  and a free end of the resilient piece correspondingly engage in the ring-shaped retaining slot of the mounting pole  151 . One end of the supporting portion  1511  abuts the top end of the collar  3519 , and the expansion cards  33  are received in the corresponding slots  153  of the motherboard  15 , completing assembly of the computer enclosure. 
     For disassembly, pressure on the operating portion  3553  deforms resilient component  3559  of the sliding member  355  elastically driving the locating member  353 . The engaging portion  3537  of the locating member  353  and the resilient piece  3539  disengage from the ring-shaped retaining slot of the mounting pole  151 . The mounting bracket  30  can then be removed from the base  10 .
