## Long description

PURE BASE 501 Airflow Window Black is a compact be quiet! ATX midi-tower case designed for efficient airflow and straightforward system builds. The case combines a classic, unobtrusive exterior with a tinted tempered glass side panel that provides a clear view of internal components. It supports ATX, Micro-ATX and Mini-ITX motherboards, multiple storage drives (2.5" and 3.5"), and offers room for high-end graphics cards and large CPU coolers despite its compact dimensions.
Advantages
The chassis emphasizes core functionality with a reduced, classic appearance and efficient space usage. A pre-installed Pure Wings 3 140mm PWM fan features seven blades optimized for high airflow while minimising turbulence and noise. The front supports up to three fans or a radiator up to 360mm, and the top supports up to two fans or a 240mm radiator. PCIe slots can be rotated 90° to allow vertical GPU installation when used with an appropriate riser cable. Front I/O includes a USB 3.2 Gen 2 Type-C connector and two Type-A ports for modern connectivity.

Compact gaming and workstation builds with ATX, Micro-ATX or Mini-ITX motherboards
Systems requiring high airflow and multiple front/top radiators (up to 360mm front / 240mm top)

How to use

Fit the CPU cooler and graphics card, taking advantage of the case's support for long GPUs and tall coolers. Add additional front or top fans or radiators as required for improved cooling. For vertical GPU orientation, rotate the PCIe slots 90° and use a compatible riser cable; ensure the riser cable's support or foam base is used to reduce GPU sag.
Usage recommendations
For optimal thermal performance, combine the pre-installed 140mm Pure Wings 3 fan with additional front intake fans and a top exhaust configuration. Use the glass side panel to monitor cable routing and component clearance; route cables through the integrated channels to maintain unobstructed airflow.
