Compact, silent and ARGB
The be quiet! Pure Base 501 LX is a mid-tower case with a silent design that allows you to assemble almost any configuration based on a mini-ITX, micro-ATX or ATX motherboard. The optimised interior space can accommodate up to 5 SSDs, a 178 mm high fan and a 368 mm graphics card. The tempered glass side panel offers an unobstructed view of the components inside your PC case, and the ARGB backlighting adds a touch of assertive gaming.
Be Quiet! has taken care to ensure quiet operation by installing four Light Wings LX fans , while emphasising its gaming look with ARGB. It also offers numerous cable management options to hide unwanted cables and optimise airflow.

Elegance and style
The Pure Base 501 LX Black is designed for fans of ARGB backlighting. With 4 Light Wings LX PWM fans pre-installed, this case will be your next favourite. With countless modes and colours and the ability to synchronise your ARGB effects, the Pure Base 501 LX has everything you need. To support a complete ARGB ecosystem, a hub for 6 ARGB devices and PWM fans is installed behind the motherboard tray.
Ultra-quiet operation
Four Pure Wings LX PWM fans are pre-installed in this case. Designed to provide optimum airflow, the Light Wings LX PWM fans are an ideal choice for any case configuration requiring high cooling performance.
The Light Wings LX PWM's 7 airflow-optimised blades not only reduce noise-causing turbulence, but also ensure the required level of cooling in the most demanding configurations. 3 Light Wings LX 120 mm PWM fans draw in cool air from the front, while a large 140 mm fan exhausts hot air from the rear.


A neat interior
Despite its compact dimensions, the Pure Base 501 LX offers enough space for high-end graphics cards and the largest radiators. Up to 3 fans or a 360 mm radiator can be fitted at the front, while the top panel can accommodate up to 2 fans or a 240 mm radiator.
The PCIe slots in the Pure Base 501 LX can be rotated through 90°, allowing the largest high-end graphics cards to be installed vertically (riser required, not supplied). The spacing is perfect for the optional be quiet! Riser Cable, whose foam base provides excellent anti-sag support for vertically oriented graphics cards.
