be quiet! Pure Base 501 Airflow Window Black Case ATX

be quiet! Pure Base 501 Airflow Window Black is a middle tower case aimed at mid-range and more serious gaming and work configurations. It supports standard formats ATX, Micro ATX, and Mini ITX, giving you freedom in choosing a motherboard. The side panel made of tempered glass provides visibility to the components without sacrificing strength. The focus is on good airflow with factory-installed two 140mm Pure Wings 3 PWM fans, plus many options for additional fans.

What you get: A chassis with a balanced size, in which you can fit most modern graphics cards up to 368 mm, without worrying that they will hit the front. The huge maximum for CPU air coolers of 178 mm allows you to install quite massive tower coolers. With up to 2 x 3.5" and 5 x 2.5" slots, you can combine a large HDD for storage with several SSDs for the system and games. The two included 140mm PWM fans (one in the front, one in the back) provide a ready-made basic airflow path “front-to-back”, and the many fan positions leave you room to upgrade cooling according to the hardware and noise you tolerate. The I/O panel with USB 3.2 Gen 2 Type-C and two USB 3.2 Type A covers modern peripheral devices well.

• Support for ATX, Micro ATX, and Mini ITX motherboards, giving you flexibility for different builds – from compact to more serious gaming systems.
• Form factor Middle Tower with 7 expansion slots, enough for standard GPUs and additional cards like capture, sound, or network.
• Fan positions: front 2 x 140 mm or 3 x 120 mm, top 2 x 140 mm or 2 x 120 mm, back 1 x 140 mm or 1 x 120 mm – a good foundation for a strong airflow build.
• Included are 2 x Pure Wings 3 140mm PWM fans (one in the front and one in the back), so you have ready cooling right from the start without additional investment.
• Side panel made of tempered glass, which shows the hardware and RGB, but remains more resistant than regular acrylic.
• Storage options with 2 x 3.5" and 5 x 2.5" slots – convenient if you want to combine a large volume HDD for data with several SSDs for quick access.
• Support for graphics cards up to 368 mm and air coolers up to 178 mm, which is enough for most modern high-end CPU and GPU combinations.
• Supported power supplies up to 200 mm, so you can comfortably install a more powerful PSU, as long as it is not excessively long.
• Modern I/O panel with 1 x USB 3.2 Gen 2 Type-C, 2 x USB 3.2 Type A, and HD Audio, so you don't have to constantly rely on the ports on the back panel.

Who is it suitable for: If you are planning a gaming or work build with an ATX motherboard, a serious graphics card, and care about good airflow, this case fits well. It is also suitable for configurations with more storage, where you need several SSDs plus a large HDD. It is not the best choice if you are aiming for an extremely compact machine or already have a very long PSU with limited cable space.

The combination of decent size, airflow-oriented design, two 140mm PWM fans, and a glass side panel makes the Pure Base 501 Airflow Window Black a practical choice if you want a tidy and well-cooled build without unnecessary compromises.
