## Long description

Pure Base 501 Airflow White is a compact ATX PC case from be quiet! that combines a classic, unadorned exterior with efficient airflow design. The case accommodates high-end hardware despite its reduced footprint and includes front and top mounting options for multiple fans or radiators, plus modern front I/O connectivity for fast data and power delivery.
Advantages
The case offers a timeless appearance focused on core functionality and quiet operation. It ships with a Pure Wings 3 140mm PWM fan optimized for high airflow and reduced turbulence, enabling effective cooling for demanding configurations. Space-efficient internal layout supports large graphics cards and tall CPU coolers while providing options for vertical GPU mounting using rotatable PCIe slots. Front I/O includes one USB 3.2 Gen 2 Type-C and two USB Type-A ports for contemporary connectivity.

How to use
Install motherboard and power supply according to manufacturer instructions and use the integrated cable routing channels to organize cables behind the motherboard tray. Mount cooling components in the front or top areas according to desired airflow: up to three fans or a 360 mm radiator at the front, and up to two fans or a 240 mm radiator at the top. If installing a graphics card vertically, rotate the PCIe slot assembly 90° and use an appropriate riser cable; ensure the riser cable and GPU are securely supported to prevent sagging.
Recommendations
For optimal cooling performance and low noise, pair the case with high-airflow fans and a compatible radiator size for your front or top mounting. When using vertical GPU mounting, use a supported riser cable and check clearance for cooler height and GPU length before final assembly.
