Who each one is for
The be quiet! Pure Base 501 suits noise-sensitive builds and home office or shared-room PCs, though it is the wrong buy for high-wattage GPU airflow builds and showcase RGB aesthetics. The Corsair Frame 4000D is the one to take for builders who want to change the case's aesthetic later and standard ATX gaming builds wanting 360mm front radiator room, though it is not the pick for budget builds where the panel kits aren't worth the premium and builders who already know exactly which panel style they want. Our rating of the be quiet! Pure Base 501 (7.5/10): A solid, unfussy silent case for people who want lower noise more than they want RGB or max airflow. Our rating of the Corsair Frame 4000D (7.5/10): A smart idea for anyone who isn't sure whether they want mesh or glass yet, though it's a premium over the regular 4000D Airflow for the same base performance.
