Dense Mesh Airflow Design
The AX20’s standout feature is its slanted bar air intake design, which pairs a dense mesh front panel with massive airflow potential. This design not only maximises cooling efficiency but also prevents dust from entering the chassis. Combined with the half-view tempered glass side panel, it offers both performance and visual appeal for gaming setups.
Versatile Cooling Configurations
Supporting up to 8 x 120 mm fans simultaneously, the AX20 provides extensive cooling flexibility. The front panel accommodates three 120 mm fans, while the top and rear offer additional mounting points for balanced airflow. Whether you’re running air cooling or planning a liquid cooling loop, this chassis adapts to your thermal management needs.
Compact Yet Spacious Interior
Despite its midi tower footprint (207 x 358 x 451 mm), the AX20 offers impressive internal space. It supports graphics cards up to 27 cm in length and CPU coolers up to 15.5 cm tall, making it suitable for high-performance gaming builds. The seven expansion slots provide room for multiple GPUs or add-in cards without compromise.
