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.

Questions about this item

What motherboard form factors does the Pure Base 501 Airflow support?

The case accepts ATX, Micro ATX and Mini ATX motherboards, so your board must match one of those three sizes.

Can I keep my existing 3.5-inch hard drives and 2.5-inch SSDs when moving to this case?

How do I confirm the pre-installed 140 mm PWM fans are running after I build the system?

Connect the fan headers to the motherboard, then check fan speed readings in the BIOS or monitoring software to verify they are spinning.
