The Phanteks XT M3: Slim Mini Case for Your Gaming Setup
Show off your gaming hardware with the Phanteks XT M3 – a compact SFF case designed for big ambitions. Compatible with high-end graphics cards and back-connect motherboards, this tower is ready for your modern setup.

Efficient Cooling With Fans and Radiator
The Phanteks case supports the installation of up to nine fans – keeping your build cool under all loads. Three fans can be mounted on the bottom panel, directly beneath the graphics card, to provide extra cooling for your GPU.
There’s also room on the top panel for a 360mm radiator if you prefer liquid cooling.
In addition to fans and a radiator, the mesh front panel ensures excellent airflow, reducing the build-up of hot air inside your case.
Your New Gaming PC With Clean Cable Management
Routing cables neatly isn’t always easy – but with the Phanteks XT M3, cable management is a breeze. Well-placed cut-outs make it easy to route your cables cleanly. Combined with support for motherboards with back-connect design, you get a tidy build that looks great and improves airflow at the same time.
Mini-ITX Case Built for Powerful Hardware
Even a large graphics card fits without issue – the case supports a GPU up to 430mm in length. Note that you won’t be able to install front fans if you use the full GPU length. The CPU cooler should not exceed 175mm in height, and the power supply should be no longer than 150mm.
