Antec CX300M ARGB Gaming Case

The Antec CX300M ARGB is designed for compact gaming builds and mid-sized rigs where style meets performance. With panoramic glass panels and vivid ARGB lighting, it transforms your internal hardware into a showcase while providing solid cooling and radiator/fan support for performance-focused systems.

The CX300M ARGB features a full-view side and front tempered-glass design to display hardware beautifully. It includes vertical-cooling architecture that supports up to nine fans, accommodating top, side, bottom, and rear mounts. The case supports up to a 360 mm radiator on top or a 240 mm one on the side, giving flexibility for liquid-cooling setups. EVA cushion pads under the PSU mount help reduce vibration and noise.
