The Phanteks XT M3: Sleek Mini Case for Your Gaming Setup
Showcase your gaming hardware with the Phanteks XT M3 – a compact SFF case built for greatness. Compatible with high-end graphics cards and back-connect motherboards, this tower is ready for your next-gen build.

Effective Cooling With Fans and Radiator
The Phanteks case supports the installation of up to nine fans – ensuring your build stays cool even under heavy load. Three of these fans can be mounted on the bottom panel, directly beneath the graphics card, providing extra cooling for your GPU.
You can also mount a 360mm radiator on the top panel if you prefer liquid cooling.
In addition to fans and a radiator, the mesh front panel ensures excellent airflow, preventing heat build-up inside your case.
Your New Gaming PC With Clean Cable Management
Keeping your cables tidy can be a challenge – but with the Phanteks XT M3, it’s remarkably easy. Thoughtfully placed cut-outs make routing cables a breeze. Combined with support for back-connect motherboards, you’ll get a clean build that not only looks great but also improves airflow.
Mini-ITX Case Built for High-Performance Hardware
Even large graphics cards are no problem – the case supports a GPU up to 430mm in length. Note that front fan installation is not possible if you use the full GPU length. The CPU cooler height should not exceed 175mm, and the power supply should be no longer than 150mm.
