Asus X73S HDD Sledge Assy

Asus X73S comes with a free space for another 2.5'' hard disk drive, but the manufacturer does not provide a sledge to mount another drive. This is my solution. It is not exactly the same, but it fits as it should.
Additional M2.5 and M3 metric screws with a flat head (bugle head) are necessary to screw it all together.
