I checked out the Tom's Hardware case review just posted on the site. To my astonishment i found this little gem in the review. For those of you who doesn't get it right away, the shockproof pads he is referring to is preinstalled rubber grommets for damping vibrational noise from the harddrive.
"Also included were shockproof pads on the 3-½ hard drive cage to help protect the hard drives from damage due to transit. This should be a welcomed innovation to gamers who regularly attend LAN parties and are always worried about crashing their hard drive due to movement. While we are not sure how much additional protection this strategy offers, it is nice to see the Compucase team trying to come up with innovative ideas to at least try to address this."
