The striking feature of the Level 20 GT PC tower chassis involves four tempered glass panels with locking hinged doors, allowing for a view of the hardware installed inside. It supports ATX motherboards and integrates a patented PCI-E slot design and a removable power supply cover. Two 200 mm front fans with digitally addressable RGB illumination and a 140 mm rear fan are pre-installed at the factory. The illumination is piloted by the included controller hub.
