An exemplary housing for a hard disk drive includes an enclosure, a bracket slidably mounted in the enclosure, and a panel mounted to the bracket. The bracket supports the hard disk drive thereon. The panel includes a cover pivotably connected to the bracket and an operation bracket mounted to the cover. The panel can be rotated to a closed status where the operation bracket is pulled by a spring to lock with the enclosure, thereby to fix the cover to the enclosure. The panel can also be rotated to an open status where the operation bracket is detached from the enclosure, whereby the bracket can slide out of the enclosure to expose the hard disk drive.
