Vantec NexStar NST-355UF 3.5" External HD Enclosure
 

One of the significant changes to the product is the repositioning of the
Power and HD LED display from the rear of the unit to the front. With the
NST-350UF, consumers had only one single LED as a visual queue for Power
and HD activity. The new unit expands this feature by using a series of
blue coloured LEDs. The enclosure of the NST-355UF also includes a series
of ventilation slots which run down the left and right hand side of the
unit. The ventilation slots address concerns with air circulation and
cooling once a HD is installed into the unit.
