Minimalist elegance, controlled silence, and intelligent modularity. The Be quiet! Pure Base 500 Window White (ref. BGW35) embodies the perfect balance of understated design, thermal performance, and quiet operation. Designed for demanding users, this mid-tower case offers a versatile platform for ATX, Micro-ATX, and Mini-ITX configurations, while showcasing components through its tempered glass side window. Its sleek matte white design integrates harmoniously into any environment, whether office or gaming. The glass side panel highlights the internal components, making it ideal for RGB setups or neat builds. Inside, the layout is optimized for airflow, featuring two pre-installed 140 mm Pure Wings 2 fans that ensure silent and efficient cooling. The case includes multiple drive bays (up to 5 × 2.5" and 2 × 3.5"), a power supply cover for a clean aesthetic, and ample space for graphics cards up to 369 mm. It is also compatible with liquid cooling systems, accommodating radiators up to 360 mm at the front and 240 mm at the top. Modularity is at the heart of its architecture: the storage mounts are removable, the dust filters are easily accessible, and cable management is facilitated by well-positioned pass-throughs. Assembly is intuitive, even for beginners.
