Antec P150 Quiet PC Case
 

The hard drive bays are one of a kind in a manufacturer's offering. Using an
old modders trick for suspending hard drives (albeit somewhat better looking
than using twisted pantyhose or rubber bands) the case can be completely
isolated from hard drive vibration which is a major source of noise in all
computers. Using this setup, 3 hard drives can be installed. If the user
prefers, the hard drives can be installed on the Antec drive racks with the
provided extra long screws. The hard drive will sit on top of 4 tall silicone
grommets, ultimately more secure than the rubber bands but slightly noisier.
