ASUS A21 Plus Micro-ATX Cases, supports BTF

The ASUS A21 micro-ATX case is compatible with BTF motherboards for clean cable management. It also offers support for 360mm radiators, a 380mm graphics card and CPU cooler up to 165mm in height.

ASUS A21 is available in Black or White

BTF COMPATIBLE

The most unique aspect of the ASUS A21 chassis is that it allows support for both standard and BTF micro-ATX motherboards. The benefit of a BTF motherboard is that their motherboard connections are on the underneath of the motherboard which allow for a very clean build. The only cable that would be visible is the graphics card power cable, assuming a graphics card is installed.

DISCOVER HIDDEN POTENTIAL

The ASUS A21 is a PC case crafted for minimalist mainstream DIY PC builders, with support for a variety of AIO coolers and graphics cards, and plenty of airflow potential to keep things running smoothly.

BROAD COMPATIBILITY

Despite being a micro-ATX case, the A21 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 is 40% porous to maximise the balance of airflow and RGB visibility. Users can add up to three 120 mm fans to this section of their build to solidly manage system temperatures.

AMPLE CABLE MANAGEMENT

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

FRONT I/O PORTS

At the front top of the A21 you’ll find two USB 3.2 Gen1 Type-A ports along with separate headphone and microphone ports.
