Antec CX300 ARGB ATX Mid Tower Case

The Antec CX300 ARGB is a mid-tower PC case designed for builders who want a visually striking, well-ventilated enclosure without compromising on component compatibility. Its standout feature is a panoramic 270-degree view achieved through full-panel tempered glass on both the left side and front, giving you an unobstructed showcase of your internal hardware. The glass is non-drilled and 4mm thick on the side panel, contributing to a clean, seamless exterior aesthetic. Thermal performance is a priority in the CX300 ARGB. The case draws air through mesh panels on the bottom and side, promoting efficient heat dissipation across the entire build. It ships with four 120mm ARGB fans pre-installed — three reverse-mounted fans on the right side panel and one standard fan at the rear. The daisy-chain synchronisation lets you link all four fans through the main fan controller for unified ARGB lighting effects. Builders planning a liquid-cooled system will appreciate the broad radiator support: up to 360mm at the top and 240mm on the side. Note that when a top-mounted radiator is installed, memory height is limited to 45mm due to potential clearance conflicts. The case can accommodate up to ten 120mm fans simultaneously across the top, side, bottom, rear, and PSU shroud positions, offering extensive airflow customisation. Component clearance figures are generous: graphics cards up to 420mm in length, CPU coolers up to 170mm in height, and power supply units up to 245mm (including cables) are all supported. Seven expansion slots are available for multi-GPU or expansion card configurations. Storage options include two 3.5-inch HDD bays and three 2.5-inch SSD positions (one combo bay plus two dedicated). Dust filters at the top and bottom help keep internals clean over time. The front I/O panel provides quick access to power and LED control buttons, two USB 2.0 ports, one USB 3.0 port, and a combined microphone/HD audio jack. EVA anti-vibration foam pads on the PSU mount position reduce resonance from power supply operation. Ample internal cable routing space keeps wiring organised and airflow unimpeded.
