A great deal of PC case feet are solid plastic and therefore do a good job of transmitting unwanted vibrations from inside a PC via the chassis/case into the desk, floor or shelf on which the system sits. In this situation, where the case is in direct contact with the substrate, the PC can generate annoying noise elsewhere (secondary noise).

Provides better surface traction for pc case or other equipment enclosures.
