A computer bezel includes a main body, a door secured to the main body, a pushing member slidably secured to the main body, and a driving member rotatably secured to the main body. The main body defines a through opening. The door is rotated between a closed position, where the door covers the through opening, and an open position, where the door is rotated away from the main body to expose the through opening. The pushing member is slid between a first position, where the pushing member is disengaged from the driving member, and a second position, where the pushing member rotates the driving member. When the driving member is slid from the first position to the second position, the driving member is capable of sliding a tray of a disk drive out of the disk drive, and the door will rotate from the closed position to the open position.
