ion from Buy.com:

Full aluminum built cooling body constructed to fit four drives within a three (5.25?) bay fitting, the MB454 Series follows the tradition of industrial systems’ needs for stability, durability, toughness and high sensitivities for mass storage operating conditions. It’s equipped with a hot swappable fan that may be detached if confined by depth limitations when integrated, or if replacement is necessary. Our removable fan requires no tools or wiring, simply swap with a new fan and back to operation! It is space saving and user friendly for industrialized system solutions.
