Abstract: An isolation mounting system attaches a computer component, such as a disk drive, to the structure of a computer system. In an embodiment, the isolation mounting system comprises a post bracket attached to the computer component, a plurality of isolators attached to posts extending from the post bracket, and a socket bracket attached to the isolators and to the structure of the computer system. An opening in the isolators fits over, onto, or around the posts of the post bracket. Outer surfaces of the isolators fit within receptacles of the socket bracket.
