The Ventilation System
Two 4.7" (120mm) fans can be mounted in the case for ventilation. Neither are included in the package, however.
Several vent holes in the case also feed air from the surroundings into the interior. A special height-adjustable plastic unit provides the CPU cooler you later install with fresh air.
