Overview

The ASUS A21 PLUS is a compact mini-tower designed for Micro-ATX and Mini-ITX motherboards. It fits high-end components with 380mm GPU clearance and extensive cooling options.

Design and Build

The black steel chassis features a tempered glass side panel to showcase internal components. A magnetic dust filter covers the top vent, and the front I/O panel is concealed behind a cover for a clean look. The case measures 220mm wide, 465mm high, and 430mm deep, weighing 8.1 kg.

Cooling Performance

The interior accommodates up to seven 120mm fans or four 140mm fans across top, front, and rear positions. Four ARGB fans come pre-installed at the front and rear. Both the top and front support radiators up to 360mm, while the rear accepts a 120mm radiator.

Component Compatibility

The case fits graphics cards up to 380mm long, covering most current high-end models. CPU coolers up to 165mm tall are supported. ATX power supplies up to 210mm in length mount at the bottom rear. Five expansion slots are available for add-in cards.

Storage and Connectivity

Drive capacity includes two combined 3.5-inch or 2.5-inch bays plus one dedicated 2.5-inch bay. The front I/O provides two USB 3.2 Gen 1 Type-A ports, a microphone jack, and a headphone jack. The chassis supports motherboards with back-connect connectors for cleaner cable routing.
