Designed for high-end gaming system compatibility, the Tower 900 supports motherboards up to standard E-ATX, tower CPU coolers with a maximum height of 260mm, and multi-GPU configurations, vertically mounted, up to 400mm in length. Further, a “1+6+2” modular drive bay design allow users to easily install up to one 5.25”, six 2.5”/3.5” (with HDD cage) and two 2.5” (with HDD tray) storage devices. The removable drive device racks give users plenty of flexibility to gain maximum interior space needed for maximum cooling performance and proper cable management improving overall case ventilation.
Unparalleled Cooling Ability
The Tower 900 has the capability to deliver excellent cooling efficiency, and enables users to build extreme air/liquid cooling systems with high-end, large graphics cards, treated by DIY/AIO liquid-cooling systems and air-cooling units. Supporting up to dual 560mm liquid cooling radiators, cooling possibilities just got real. Most uniquely, the right side and left side of the case are designed with various mounting points for radiators to provide proper space and placement when building DIY/AIO configurations.
