Remember Newton's first law? The thing is if anything is vibrating, it doesn't matter what it is also vibrating, either parts of itself or whatever it is in contact with. Even at zero G, the vibrating thing is going to vibrate the enclosure it is contained in and the interconnects connecting it to the rest of the system.
The answer is to select quiet, well-designed components that don't vibrate so much in the first place.
