Compatible with reverse-wired motherboards.

The model can be a good choice for assembling a powerful gaming platform on a micro-ATX motherboard. At the same time, the chassis is spacious enough to mount a professional video card up to 380 mm long inside. The case is well compatible with modern and high-performance GPUs of the Nvidia RTX 4090 and AMD Radeon RX 7900 class. The Asus A21 gaming case is designed to organize good air exchange for the chassis.

The front cover has the appearance of an easily removable mesh with a magnetic fastening. The façade mesh provides a ventilation rate of 40%, simultaneously filtering out large particles of dust and insects from the air. The perforated covers on the top and bottom are also equipped with dust protection. There is 33mm of free space between the motherboard plate and the side panel.

This is enough for safe and convenient installation of connecting cables. The installation location of the power supply is separated from the main part of the chassis by a partition. The power supply installation unit is combined with the memory storage rack. To work with removable media and mobile devices, two USB 3.2 gen1 ports are allocated. The case has a top mounting platform to accommodate a powerful 360 mm SVO radiator. You can install three 120mm fans at the front.
