be quiet! Silent Base 802 Black Mid Tower Case BG039
The be quiet! Silent Base 802 Black is a mid-tower case designed for builders who want whisper-quiet operation without sacrificing cooling performance.

Best for
- Water-cooling builders who want noise control
- Silent office or media centre builds with aggressive cooling included
- Systems with multiple storage drives or high-capacity arrays
- Builders who value flexibility to switch between quiet and airflow modes
Trade-offs
- Mini-ITX or compact builds—this is a full mid-tower at 539 × 553 × 281 mm
- Standard air-cooled systems without intent to upgrade cooling, where the pre-installed fans and modular design add unnecessary cost
- Users who prioritise maximum GPU length without compromise—287mm with HDD cage leaves little headroom for flagship cards
The be quiet! Silent Base 802 Black is the perfect solution for sophisticated users who strive for whisper-quiet operation and maximum performance alike.
INTERCHANGEABLE TOP COVER — 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.
INTERCHANGEABLE FRONTPANEL — 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.
The Silent Base 802 supports E-ATX, ATX, micro-ATX, and mini-ATX motherboards, giving you plenty of options when it comes to component choice. With seven horizontal and two vertical PCI expansion slots, you can install a wide array of utility and graphics cards up to 17 inches long. With the HDD cage installed, you can install a graphics card up to 11.3 inches long.
Mount solid-state and hard disk drives with seven 2.5 and three 3.5" drive bays, which can be expanded up to fifteen and seven bays respectively with additional hardware. A robust front panel gives you access to a USB 3.2 Gen 2 Type-C port, two USB 3.2 Gen 1 Type-A ports, two 3.5mm audio jacks for headphones and mics, and a fan switch. Additionally, the Silent Base 802 includes front and bottom dust filters that keep your system tidy and clean.
