Bad decoupled

The decoupling is not satisfactory. Between cage and hard drives Although gums are attached, but between the cage and the remaining case is direct contact. Unfortunately, the vibration is not sufficiently absorbed by the rubber, so that with me at least after installing 2 HDDs the entire casing is vibrated rhythmically - with plenty of space as a resonance chamber. That does not bother then the more than a constant background noise as it occurs by fans.
