A computer enclosure includes a cage ( 10 ), an upper plate ( 100 ), two expansion bodies ( 140 ), and two operating devices ( 200 ). The cage has a chassis ( 12 ), a frame ( 16 ) received in the chassis, and an anti-EMI plate ( 18 ) attached onto the frame. Two recessed portions ( 102 ) are formed in the upper plate for accommodating the expansion bodies. The operating devices are attached to opposite sides of the chassis. Each operating device has a releasing device ( 202 ), a driving device ( 204 ), and a controlling device ( 206 ). When a button ( 258 ) of each controlling device is pressed inwardly and then pushed forwardly, a driving plate ( 254 ) of the controlling device drives the driving device to release the corresponding expansion body from the upper plate. When the buttons of the controlling devices are pressed inwardly and then pushed rearwardly, the driving plates drive the releasing devices to release the frame from the chassis.
