be quiet! BGW74 Pure Base 501 Airflow Window Mid Tower Case
The be quiet! BGW74 Pure Base 501 Airflow Window is a compact mid-tower case designed for builders who want excellent thermals and clean aesthetics without excess size or noise. It fits high-end graphics cards and large CPU coolers while maintaining a practical footprint, and ships with two pre-installed fans optimized for airflow.
Why this product
Optimized airflow with pre-installed fans
Two Pure Wings 3 140mm PWM fans come installed to maximize air pressure and cooling performance. The front intake and top exhaust design supports radiators up to 360mm front and 240mm top.
Fits high-end GPUs and coolers
Maximum GPU length of 368mm and CPU cooler height of 178mm accommodate current flagship components. Optional vertical GPU mounting with rotating PCIe slots offers further flexibility.
Compact, practical dimensions
At 450 × 231 × 463 mm, it is smaller than full towers yet supports ATX motherboards and extensive storage, making it suitable for desk-side or space-limited builds.
Fast front connectivity
USB 3.2 Gen. 2 Type C port plus two Type A USB 3.2 ports on the front I/O panel provide modern, high-speed device access without reaching the motherboard.
Tempered glass side panel
A transparent side panel lets you display internal components and lighting while the steel frame and ABS construction maintain rigidity and durability.

Trade-offs
- E-ATX or extended motherboards: designed for ATX and smaller only; larger boards will not fit.
- Extreme multi-GPU setups: limited to single-GPU layout; dual-card configurations are not supported.
- Builders needing many 3.5" drives: only two removable 3.5" bays; SSDs up to five 2.5" instead.
- Very large power supplies over 200mm: maximum PSU length is 180mm (or 200mm only if HDD cage is removed).
