Antec has been a foundation of the PC case market for decades, with an incredible range of PC cases that span back to the early days of custom PC building, from budget models for the office and PC gaming, all the way up to flagship monsters built for the absolute best hardware on the market, not only in previous years and decades, all the way up to the modern day. Now, with the Antec C6 Curve Air, they’re ticking all the boxes for the modern PC gaming enthusiast yet again!
The C6 is a panoramic mid-tower chassis designed to showcase high-end hardware while maintaining the cooling demands on high-end hardware, as graphics cards and CPUs are more powerful than ever, airflow remains a key focus for any PC build in 2026. By utilising a three-sided tempered glass design, it offers an unobstructed view of your components, making it an ideal candidate for enthusiasts who want strong aesthetics in their build too. With support for large GPUs such as the biggest RTX 5090s or 9070 XT graphics cards on the market, the latest back-connect (BTF) motherboards, the case is built to handle modern, power-hungry systems, so I’m eager to dive in and take a closer look!
Features
The design of the C6 Curve Air focuses heavily on airflow, despite its triple glass design. It employs a bottom-to-top vertical cooling configuration, assisted by recessed dual fan mounts located on the power supply shroud. The inclusion of a fine mesh top panel, combined with extensive ventilation across the front and sides, ensures a consistent intake to keep temperatures under control. Furthermore, the chassis incorporates tool-free panels, extensive cable management features, such as integrated rubber grommets and Velcro straps, ensuring you get a clean looking build with ease.
