- MULTIPLE COOLING OPTIONS - The bottom panel supports up to two 120mm fans; the rear a 120mm fan or 120mm radiator; the top up to two 120mm/140mm fans or a 120/240mm liquid cooler radiator.
- EDGE-TO-EDGE DISPLAY - The square edge-to-edge transparent side panel enables a full display of any system build, and includes an I/O panel which can be rotated into 3 different orientations on either side. Behind the motherboard tray is 28mm of allocated space for clean cable management.
- SUPPORTS STANDARD ATX - When housing a standard ATX motherboard, the PSU is mounted to the top-front of the chassis inside a height-adjustable bracket. For mini-ITX builds, the PSU can be placed in the conventional bottom-rear position for increased front panel ventilation.
