Abstract: A computer enclosure (100) includes a cage (50) and a drive bracket (10). The cage includes a base wall (60), and two side walls (62) extending upwardly from the base wall. A box-shaped supporting portion (64) is formed from a front edge of the base wall. A top portion of a front edge of each side wall extends inwardly and rearwardly to fold back over itself and form a fastening device (66). Each fastening device includes two symmetrically opposing L-shaped portions (68), and a sliding space (69). A pair of L-shaped latches (20) is outwardly stamped from each of opposite side plates (14) of the drive bracket, for being received in the sliding space of the corresponding fastening device. A plurality of apertures (74) is defined in the supporting portion in alignment with a plurality of holes (24) of the drive bracket, for extension of screws therethrough.
