Is anyone familiar with Silenx's rubber grommets that make HDDs and optical drives reduce vibration? If they work or not is irrelevant at this point, I just can't get the darn things in! My HDD is housed in a metal cage and it's metal touching metal. There is no way I can see to cram even a human hair between the HDD and it's housing, let alone a rubber grommet. Maybe they are just designed for a different setup than mine.
