Antec Constellation Series C6 Curve ARGB Black ATX Mid-Tower Case

The Antec C6 Curve ARGB is an enthusiast-grade mid-tower chassis combining a three-sided curved tempered glass panoramic display with dynamic addressable RGB lighting and a vertical bottom-to-top cooling architecture. Designed without obstructive front corner pillars, it offers an expansive visual stage for flagship components. Engineered around a floating graphics card layout, it effortlessly accommodates large-format GPUs up to 450mm in length—including the flagship NVIDIA GeForce RTX 5090—preventing physical interference with side-mounted components. Out of the box, cooling is driven by three pre-installed ARGB PWM fans: two 120mm reverse-flow fans recessed onto the PSU shroud (supplying dedicated intake airflow directly to the GPU) and one 140mm rear exhaust fan. Purpose-built for clean cabling, it provides native support for back-connect motherboards (BTF / Project Zero), an innovative 90° rotatable PSU mounting module paired with an included 13A high-spec internal extension cable, 30mm of rear routing depth, and comprehensive tool-less panel access across the chassis. Accommodating top liquid radiators up to 360mm, the Antec C6 Curve ARGB is backed by a 2-year warranty.

Key Features

• Three-Sided Curved Tempered Glass: Continuous 4mm curved tempered glass architecture delivers a panoramic perspective of the entire interior without structural pillars.
• Three Pre-Installed ARGB PWM Fans: Factory-fitted with two 120mm ARGB PWM reverse fans on the PSU shroud to feed direct positive air to the GPU, plus one 140mm ARGB PWM rear exhaust fan.
• Vertical Cooling & Multi-Directional Airflow: High-capacity ventilation across the front, sides, and lower chamber draws cool ambient air upward and exhausts smoothly through the fine mesh top panel.
• GeForce RTX 5090 Ready: Floating GPU architecture provides up to 450mm of clearance, preventing physical interference with side-mounted components.
• Back-Connect Motherboard Support: Engineered with precise pass-through cutouts for back-connect motherboards (BTF / Project Zero) to achieve a zero-cable interior appearance.
