Pure Base 501 Airflow ATX full tower
The Pure Base 501 Airflow is a compact ATX full tower built from ABS, steel and tempered glass. It supports ATX, micro-ATX and mini-ATX motherboards and comes in a black finish. Two pre-installed Pure Wings 3 140 mm PWM fans provide high static pressure for demanding airflow. Front-panel I/O includes one USB 3.2 Gen 2 Type-C, two USB 3.2 Type-A and combined HD audio.
Who this suits and who should look elsewhere
Builders who want strong airflow in a restrained footprint will appreciate the mesh front and top panels. The case fits graphics cards up to 368 mm and CPU coolers up to 178 mm, so most high-end components install without compromise. Radiator support reaches 360 mm at the front and 240 mm at the top for custom loops. Users needing more than two 3.5-inch bays or a lighter chassis should consider other models.
Capacity and headroom
Internal storage offers two 3.5-inch bays and five 2.5-inch mounts for mixed SSD and HDD layouts. Seven expansion slots handle full-length add-in cards and optional vertical GPU mounting. The power-supply compartment accepts units up to 180 mm deep. Cable routing channels keep the interior tidy while maintaining clear airflow paths to the top and front radiators.
