Phanteks introduced the EX5 lineup, its first chassis models in the new EX Series, at Computex 2026. The EX5 features an innovative compartmentalized architecture that delivers fresh airflow directly where needed while efficiently exhausting heat, reducing the need for excessive fan configurations. This design helps builders reduce system costs while maintaining efficient cooling.

The chassis supports graphics cards up to 358 mm in length and provides dedicated 360 mm radiator support across all models. A strategically positioned rear mainboard fan provides direct airflow to the VRM and RAM while directing GPU heat away from surrounding components. The EX5 lineup includes three configurations: EX5, EX5 PLUS, and EX5 MAX, with the latter two featuring the integrated Glacier One 360S25-SE AIO with concealed tubing for a streamlined 'no-tubes' aesthetic.

The EX5 MAX adds a 6-inch high-resolution display for real-time system monitoring. Phanteks' design emphasizes cable management, integrated ARGB lighting, and NEXLINQ ecosystem compatibility for synchronized control.
