be quiet! Dark Base Pro 901 White is a full tower case for serious builds where you want silence, airflow, and space for large hardware. It supports almost all popular motherboard formats – from Mini ITX to Extended ATX, giving you freedom for future upgrades. The tempered glass side panel showcases the configuration, and inside there is space for a graphics card up to 370 mm and a cooler up to 190 mm. This is a high-end case aimed at powerful gaming and workstation systems, without a built-in PSU, so you can choose the right power supply for your build.

What you get
The large volume of the full tower form factor and good fan support allow you to build serious airflow – from the front, top, bottom, and sides, so warm air has no chance to linger. The case comes with 3 included fans, saving you initial costs and providing a solid foundation for decent airflow. With up to 8 expansion slots, you have room for thicker GPU configurations, additional expansion cards, or capture cards. For storage, you have 2 slots for 3.5" drives and up to 8 for 2.5", which is more than enough for a combination of large HDDs for archiving and fast SSDs for gaming and work. The built-in fan speed control on the front I/O allows you to adjust the fan speeds directly from the case – convenient when balancing between silence and cooling.
