The decoupled motherboard tray adapts to suit individual requirements, being completely relocatable and usable as a test bench. You can adjust it to three different heights or install it alongside the left panel in an inverted layout with redefined airflow. It is fully compatible with E ATX and XL ATX motherboards. The three pre installed SilentWings 3 140mm PWM fans offer virtually inaudible operation. They are equipped with a smooth running 6 pole motor, durable fluid dynamic bearing and airflow optimized fan blade design. The frame has funnel shaped air inlets that generate high air pressure. The installation options are flexible thanks to repositionable single HDD slots. Supports up to 7 HDDs, 15 SSDs and 2 optical drives. The assembly and handling concept gives you modularity choices, empowering you to create systems that meet the highest of standards.
