be quiet! Silent Base 802 Window White Midi Tower PC Case

The be quiet! Silent Base 802 Window White is a mid-tower PC case designed for users who require a balance of low noise, strong cooling potential and flexible configuration options. It includes interchangeable top covers and front panels to optimize either silence or high airflow, three preinstalled Pure Wings 2 140 mm fans, extensive sound-damping materials and a tempered glass side window that reveals the interior components.

Advantages

The case provides configurable airflow and silence through interchangeable top and front panels, allowing choice between maximum cooling performance or whisper-quiet operation. Thick 10 mm dampening mats on the front and sides plus decoupled mounts reduce vibrations and noise. A USB 3.2 Gen 2 Type-C front port and a built-in 4-step fan controller add modern connectivity and manual fan-speed control. The removable, invertible and decoupled motherboard tray supports varied layouts and test-bench use, while the PSU shroud hides cables and accepts additional fans or large front radiators.

Key specifications

• Form factor: mid-tower case with full metal body
• Included fans: 3 × Pure Wings 2, 140 mm
• Top covers: interchangeable (solid for silence and high-airflow mesh for water-cooling/airflow)
• Front panels: interchangeable (standard quiet panel and high-airflow panel)
• Sound dampening: up to 10 mm mats on front and sides; decoupled PSU bracket, motherboard tray and HDD cages
• I/O: USB 3.2 Gen 2 Type-C on front I/O
• Fan control: integrated 4-step controller for up to 6 fans or single PWM signal
• Motherboard tray: removable, decoupled and can be installed inverted
• PSU shroud: covers cables and PSU, contains double HDD cage; removable plates to fit 140 mm fan or front radiators (360/420 mm)
• Side panel: tempered and tinted glass window with white painted side bars

How to use

Choose the appropriate top cover and front panel for your build: use the solid top and standard front panel for a quiet system, or the high-airflow top and airflow front panel for water cooling or maximum intake. Connect case fans to the integrated 4-step controller or to a motherboard PWM header depending on preferred control method. Install the PSU using the rear bracket, route cables beneath the PSU shroud and remove cover plates if you need to mount an additional 140 mm fan or a 360/420 mm radiator at the front. The removable motherboard tray allows inverted mounting or use as a test bench for component access during assembly or troubleshooting.

Recommendations

For low-noise everyday systems, install the standard front panel and solid top cover, connect fans to the case controller and use the thick dampening mats. For high-performance cooling or custom water loops, fit the airflow front panel and the mesh top cover, remove the small PSU-shroud cover plate if needed, and consider connecting fans to the motherboard PWM for synchronized control.
