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.
