ASUS A21 PLUS Case

The ASUS A21 PLUS microATX case offers support for hidden-connector motherboards, 360 mm radiators and 380 mm graphics cards, with two color options, four pre-installed ARGB fans and clean cable management.

- Hidden Connectors: Compatible with motherboards featuring hidden connectors and maximizes clean cable management for a clutter-free build.
- Broad Compatibility: A21 PLUS supports up to 360 mm radiators, graphics cards up to 380 mm in length and CPU air coolers up to 165 mm in height.
- Capable Cooling: A21 PLUS features four ARGB fans for exceptional cooling, and the front-panel mesh is 40% porous to maximize the balance of airflow, dust filtering and RGB visibility.
- Ample cable management: The A21 PLUS provides a compartment behind the motherboard that is 33 mm wide to keep your wiring tucked away and tidy.

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.

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.

Great case!!

Colour: Black

Bought this case after a tonne of research... Looks super tidy. Cable management is very easy (no case bulges). Argb looks great! Airflow is very good. I don't get temperatures over 50 degrees under heavy load. Simple and easy to build in, no fuss case. Can't complain !

Case is fine. My fault for not checking the board size

Colour: Black

Can't really complain about this case other than it takes the smaller MB and not an ATX sized motherboard
