Big Features, Small Footprint.

The ASUS A21 PLUS is designed to maximize every inch of your desk space. Despite its compact footprint, it offers support for powerful hardware, including graphics cards up to 380mm long and 360mm radiators at both the front and top, ensuring your components stay cool even during the most demanding tasks.

Key Performance Features:

• BTF Ecosystem Support: The A21 PLUS is fully compatible with ASUS BTF motherboards. By hiding your connectors on the back, you achieve a cable-free look in the main chamber that makes your hardware stand out.

• Ready-to-Go Cooling: No need to buy extra fans—the A21 PLUS includes four pre-installed ARGB fans (3 front, 1 rear) that provide excellent airflow and synchronized lighting right out of the box.

• High-Airflow Design: With a mesh front panel, the A21 PLUS ensures unrestricted airflow, making it perfect for high-wattage gaming builds that demand consistent thermal performance.

• Component Clearance: Whether you are using a beefy air cooler (up to 165mm height) or a high-end power supply (up to 210mm length), the A21 PLUS provides ample room for enthusiast-grade parts.
