A mounting mechanism is disclosed. The mounting mechanism includes a chassis with an anchor member, a slide rail with a mounting slot defined therein, and a retaining member slidablly attached to the slide rail. The mounting slot is adapted to receive the anchor member. An inclined portion extends from the slide rail. A first end of the retaining member is pivotable attached to the slide rail. A second end of the retaining member retains the anchor member in the mounting slot of the slide rail. The retaining member is rotated to slide along the inclined portion of the slide rail to urge the retaining member to move away from the slide rail, to disengage the anchor member from the second end of the retaining member.
