NMedia has used a standard approach to cooling the interior of the case via a series of ventilation slots and perforated holes. The top portion includes several ventilation slots located in the center of the design. Along with the ventilation slots is an 80mm fan mount and an air duct which sits over the location of the CPU. The air duct is a new revision added to the HTPC 180BA product line and provides a direct path for air circulation and cooling.
