Optimized for air or water cooling

The first of two included top covers perfectly rounds off the design of the Silent Base 802 Black and ensures a silent operation. For all who strive for extremely powerful cooling and especially with water-cooled systems, the highly air-permeable top cover is the right choice.


Ensures maximum performance or whisper-quiet operation The airflow front panel provides maximum performance for sophisticated configurations with highest demands for low temperatures. The standard front panel is the perfect choice for silent systems and regular PC configurations. Both panels are included.


Whisper-quiet operation

Three preinstalled Pure Wings 2 140mm fans with airflow-optimized fan blades ensure perfect airflow and solid cooling no matter if you chose a high airflow or a silence optimized configuration.


Extra thick insulation for maximum stability and silence The front and sides are equipped with extra thick dampening mats of up to 10mm, resulting in maximum stability and superb noise dampening capabilities. The decoupled PSU bracket, motherboard tray and HDD cages also minimize vibrations. The full metal body provides stability for the case and improves its haptic.


State-of-the-art technology for your system

A USB 3.2 Gen. 2 Type C connector is provided on the front I/O port and allows usage of the latest hardware. The integrated 4-step fan controller allows the setting of the speed of up to six fans manually or connect all to one PWM signal.


Designed to fit individual requirements The motherboard tray is decoupled and can be installed alongside the left panel in an inverted layout. It is also removable for use as a test bench.


Offering a neat interior The PSU shroud perfectly covers the cables, PSU and contains a double HDD cage. The cover plates are separately detachable to install a 140mm fan on the top. With the small cover detached a 360mm or 420mm radiator can be installed at the front. Using the PSU bracket the power supply unit can be easily installed from behind.
