Phanteks has officially announced the release of its latest mid-tower chassis, the XT M3, following its debut at Computex 2025. The XT M3 is the newest addition to the company’s XT series, aimed at gamers, enthusiasts, and PC builders who require performance-driven features in a space-efficient form factor. It is scheduled to be available starting July 1, 2025.
The XT M3 is built around a compact ATX layout but doesn’t compromise on hardware compatibility or cooling options. It offers support for full-length graphics cards, modern Rear-Connect motherboards, and next-generation components while maintaining a minimal footprint. This makes it suitable for both high-performance gaming builds and clean, cable-managed setups.

The case features a tool-less design, allowing users to remove the side panels without the need for screws or tools. This speeds up the building process and simplifies future upgrades or maintenance. Internally, the XT M3 supports up to nine fan positions, with three 120mm M25 fans preinstalled to assist with immediate airflow out of the box. A dedicated top panel supports up to a 360mm radiator for liquid cooling setups, while the bottom panel includes three additional fan mounts positioned to provide direct airflow to the GPU.


Phanteks has also included compatibility for Rear-Connect motherboards, which route cables behind the board to improve airflow and reduce visible clutter inside the case. The internal layout accommodates modern GPUs and cooling systems with room to spare, making it future-proof for upcoming hardware releases.


Front I/O connectivity consists of one USB-C 3.2 Gen 2 port and one USB-A 3.0 port, along with standard audio jacks. The XT M3 will be available in both black and white color options. Two versions of the case will be offered: a model with three included fans priced at $69.99 USD / €69.90 / £59.99, and a fan-less version for users who prefer to choose their own cooling configuration, priced at €59.90 / £49.99 (USD pricing not announced for the fan-less model).
Phanteks positions the XT M3 as a case that balances performance, ease of use, and value. Its space-conscious footprint combined with high airflow potential makes it a strong choice for users building in tighter environments without giving up hardware compatibility or thermal efficiency. For those looking to build a new system or upgrade an existing setup, the XT M3 will be available through retailers and local distributors starting in early July.
