Discover Hidden Potential

The ASUS A21 PLUS is a PC case crafted for minimalist mainstream DIY PC builders, with support for a variety of AIO coolers and graphics cards, and the four pre-installed ARGB fans provide plenty of airflow potential to keep things running smoothly.

Hidden Connectors

In addition to supporting conventional mini-ITX and micro-ATX motherboards, the A21 PLUS is also compatible with the TUF GAMING B760M-BTF WIFI D4, whose innovative connectors and headers are located on the underside to maximize clean cable management.

Broad Compatibility

Despite being a micro-ATX case, the A21 PLUS still supports up to 360 mm radiators, graphics cards up to 380 mm in length and CPU air coolers up to 165 mm in height, giving builders plenty of options to assemble their next PC.

Capable Cooling

The front-panel mesh of the A21 PLUS is 40% porous to maximize the balance of airflow and RGB visibility. Within, four pre-installed ARGB fans ensure ample cooling.

Ample Cable Management

The A21 PLUS provides a compartment behind the motherboard that is 33 mm wide to help you keep your wiring tucked away and tidy.

Color-Coordinated Builds

Both variants of the A21 PLUS come with color-coordinated black or white internal I/O cables to compliment your build theme.
