This item is made up of two large silicon rubber blocks with embedded steel plates. One is installed on each side of the hard drive and then the unit is installed in a 5.25" drive bay. The rubber blocks will then help inhibit vibrations from the hard drive reaching the case. A must buy for anyone looking to make their case quieter!

Slapped this on my 1TB drive and slid it into an unused 5.25" bay. I didn''t screw it in because my case is lame, but it''s so snug that I didn''t even need to.
Drive is definitely quiter. Super easy to install.
Customer service was also very cool and accomodating.
Great and cheap.

I can barely hear the computer''s hd now, and was not the quietest drive in the world too.
