Abstract: A housing assembly forms a fixed disk drive module for a low profile fixed disk drive shock-mounted therein. A frame defines front and a rear endwalls and two sidewalls. Each sidewall defines on one edge a row of enclosed cover slots having receiving portions and latching portions and on the other edge a row of open cover slot openings including entry portions and latching portions. A top cover and a bottom cover each include two peripheral flanges each defining a series of locking tab formations, one series being sized and aligned to mate in a hinging relation with corresponding ones of the enclosed cover slots and the other series to enter the open cover slot openings as the top cover is rotated toward the frame. The locking tab formations of the covers are adapted to enter and engage the latching portions as the covers are longitudinally displaced relative to the frame to an enclosure position.
