## Long description

be quiet! PURE BASE 501 Airflow Window White is a compact Midi Tower ATX case designed for effective airflow and a clear internal view. The white chassis includes a tinted tempered glass side panel, supports Mini-ITX, Micro ATX and ATX motherboards, and fits 2.5" and 3.5" drives.

Use the airflow-optimized Pure Wings 3 140 mm fan positions for intake at the front and exhaust at the rear/top to maintain efficient cooling.
