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

The ASUS A21 PLUS is a PC case designed for minimalist mainstream DIY PCs. It supports a variety of AIO coolers and graphics cards, while the four pre-installed ARGB fans ensure sufficient airflow for smooth operation.

The A21 PLUS not only supports traditional Mini-ITX and Micro-ATX motherboards but is also compatible with the TUF GAMING B760M-BTF WIFI D4, which has innovative connectors and headers located on the underside to ensure clean cable management.

Although it is a microATX case, the A21 PLUS still supports radiators up to 360mm in diameter, graphics cards up to 380mm in length, and CPU air coolers up to 165mm in height, giving builders plenty of options for assembling their next PC.

The front panel mesh of the A21 PLUS is 40% permeable to maximize the balance between airflow and RGB visibility. You can install up to three 120mm fans in this area of your system to reliably control system temperatures.

The A21 PLUS features a 33mm wide space behind the motherboard where you can neatly store your cables.

Both variants of the A21 come with color-coordinated black or white internal I/O cables that match your build.
