Bequiet presented the new PC cases from the “Pure Base 501” series in a detailed video. This replaces the popular predecessors of the 500 series. With its pure base products, the manufacturer relies on a restrained design that should appeal to both players and everyone else. The new generation is divided into three models: – Pure Base 501 (90 dollars): The standard version, which works particularly quietly and is only available in black. – Pure Base 501 Airflow (95 to 100 dollars): Here the walls are more permeable to air, which offers better airflow. Available in white and black. – Pure Base 501 Airflow Window (105 to 110 dollars): Same features as the Airflow model, but with a window on the side. Also available in white and black. All three models include two pre-installed Pure Wings 3 140mm PWM fans to increase air pressure, a three-year manufacturer’s warranty and the option to install the graphics card vertically.
