5.25" bay devices are like high tech Swiss Army knives, and the capabilities have grown to the point where the number of functions that can be squeezed into a small patch of real estate on the front of a case is really rather crazy... The item up for review takes multi-tasking to a new level by incorporating a digital display with controls/alarms for three fans and three temperature sensors, with a 55-in-1 multimedia card reader, a USB port, and an eSATA connection. In my opinion, one of the best things about it is that all of these items fit into just one 5.25" bay without looking cluttered.
