be quiet! Pure Base 501 vs Phanteks P400A: which one fits your build
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 Phanteks P400A is the one to take for budget builds where front USB-C isn't a requirement and large GPU builds needing 420mm of clearance, though it is not the pick for anyone who needs front-panel USB-C and large air coolers over 160mm tall. 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 Phanteks P400A (7/10): A dated but still capable budget mesh case; worth buying only if it's discounted below current-generation alternatives like the XT Pro.
