One of the good things about the ProXStream that sets it apart from other 1kw power supplies is its small footprint. We measured the unit to be 5 1/2" in length. Most other 1kw units (and even some not as powerful) are much longer, which will cause problems with optical drives and in cases that use a top-mounted exhaust fan. Slotted vents on the "inside" of the unit provide plenty of airflow for the 80mm fan inside to draw air in, across and out the rear.
