More at the Source.Be Quiet! has introduced its new flagship PC chassis, which combines the company's expertise in building quiet PC components with extensive modularity and customization features. The be quiet! Dark Base 900-series PC cases will feature aluminum finish, whereas the Pro version will also come with LED strips as well as Qi wireless charger for mobile devices.
The new be quiet! Dark Base 900 and Dark Base 900 Pro chassis feature a modular design, which allows switching sides of the motherboard tray, adjusting its height, removing redundant HDD and ODD cages and, of course, installing any types of fans and/or liquid cooling. Since be quiet! is primarily known for silent PC equipment, the Dark Base 900 inherit numerous designs ideas from its predecessors, including internal architecture that optimizes airflow; specially designed noise intake systems; noise-cancelling side and front panels; decoupled fan, HDD and motherboards mounts to eliminate any transmission of vibration to the case and so on.
