a tray base slidably insertable into a receiving space of a chassis in a longitudinal direction, the tray base having a top surface for receiving a drive oriented in a transverse direction such that a connector of the drive rests in a connector plane that is parallel to the longitudinal direction; and

an installation lever rotatably coupled to a bottom surface of the tray base at a pivot, the pivot defining a pivot plane parallel to the connector plane, the installation lever being rotatable between a closed position and an open position, the installation lever having a shaft extending from a lever bottom surface at a position spaced apart from the pivot, the shaft defining a shaft plane parallel to the pivot plane, rotation of the installation lever from the open position to the closed position causing a distance between the pivot plane and the shaft plane to increase, the shaft being insertable into a receiving slot of the receiving space such that rotation of the installation lever from the open position to the closed position causes the connector plane to move away from the shaft plane.
