Elevate Your Build with the ASUS A21 Micro-ATX Case White
The ASUS A21 Micro-ATX Case in White is a sleek, compact chassis designed for DIY PC builders who prioritize performance, aesthetics, and clean cable management. Supporting Micro-ATX and Mini-ITX motherboards, this case is compatible with ASUS BTF (Back To The Future) motherboards, featuring hidden connectors on the underside for a clutter-free build with only the GPU power cable visible. Despite its small tower design, it accommodates high-performance components, including GPUs up to 380mm, CPU coolers up to 165mm, and radiators up to 360mm on both front and top panels. The 40% porous front-panel mesh ensures optimal airflow, balancing cooling efficiency with dust filtering and RGB visibility. With a spacious 33mm cable management compartment behind the motherboard, along with color-coordinated white internal I/O cables, your build stays tidy and visually cohesive. The front I/O includes two USB 3.2 Gen1 ports for fast connectivity, and the case supports versatile storage with one 2.5″ bay and two 2.5″/3.5″ combo bays. Weighing 7.3kg, the ASUS A21 in White combines modern design, robust cooling, and innovative BTF compatibility, making it ideal for gamers and professionals seeking a minimalist yet powerful PC setup.
