A hard disk drive (HDD) drawer includes an outer casing fixed inside a computer and an inner casing which receives an HDD therein. The outer casing has two opposite side walls defining an open front end for removably receiving the inner casing therein. Each of the side walls has a guide slot extending from the front opening to an inner end and a second slot extending from the inner end of the guide slot to a top side of the outer casing in a direction substantially normal to the guide slot. The second slot has two opposite walls. The inner casing has a handle having two side limbs pivoted thereto to allow the handle to be rotatable between an insertion position and a securing position. The handle limbs are slidably receivable in the guide slots of the outer casing for inserting the inner casing into the outer casing. The handle limbs and the guide slots and the second slots are configured and dimensioned so that when the handle is rotated between the insertion position and the securing position, an inner end of the limbs is brought into contact engagement with one of the walls of the second slots for serving as a fulcrum point in a lever system wherein the pivot of the handle serves as the reaction point and the handle which is held by a computer user is the force application point. With such a lever system, the insertion and withdrawal of the inner casing is enhanced.
