A server system includes a chassis, a first cover, and a second cover. The chassis defines an opening. The first cover is secured to the chassis and defines a recess for receiving a disk drive. The second cover is secured to the chassis. The first cover is rotatable between a first position, where the first and second covers cover the opening, and a second position, where the first cover is rotated away from the second cover. The recess is located outside the chassis when the first cover is in the first position.
