be quiet! Pure Base 501 Airflow Black Case ATX

be quiet! Pure Base 501 Airflow Black is a middle tower case that focuses on good airflow and quiet operation without unnecessary effects. It supports standard configurations with ATX, Micro ATX, and Mini ITX motherboards, so you can comfortably use it for both compact and more serious builds. Maximum graphics card length up to 368 mm and space for a cooler up to 178 mm give you the freedom for quite a massive CPU cooler and long GPU models. The included two 140 mm Pure Wings 3 PWM fans at the front and back provide a basic, well-balanced airflow right out of the box.

What you get

Serious flexibility in cooling: you can mount up to 3 x 120 mm or 2 x 140 mm fans at the front, another 2 x 120/140 mm on top, plus one 120/140 mm at the back. This means easy construction of a full airflow tunnel from front to back, without relying solely on the included fans. With 2 x 3.5" and 5 x 2.5" slots, you can easily combine large HDDs for storage and fast SSDs for OS and games. The I/O panel with 1 x USB 3.2 Gen 2 Type-C and 2 x USB 3.2 Type A gives you convenient access to fast ports at the front for flash drives, external drives, and peripherals. Support for power supplies up to 200 mm allows you to install a more serious PSU without worrying about it hitting the cages.
