Compact Micro-ATX Chassis

The Phanteks XT M3 is a compact Micro-ATX gaming chassis measuring 460 x 235 x 370 mm. It accepts Micro-ATX and Mini-ITX motherboards and ships with three 120 mm D-RGB fans pre-installed at the front and rear. A tempered glass side panel and black steel construction complete the exterior.

Build Flexibility

The interior provides one 3.5-inch bay and two 2.5-inch bays alongside four expansion slots. Cooling options include front, rear, top, and bottom 120 mm mounts, with a dedicated top location for a 360 mm radiator and triple bottom fans for direct GPU airflow. Cable routing space accommodates rear-connector motherboards, and the front I/O supplies one USB-C 3.2 Gen 2x2 port and one USB 3.0 port.

Ideal For Compact High-Performance Builds

This case suits builders who want strong cooling capacity in a small Micro-ATX footprint, especially with custom liquid loops or long graphics cards up to 430 mm. CPU coolers up to 175 mm and power supplies up to 150 mm are supported. Users needing more than one 3.5-inch drive or a larger ATX motherboard should consider a different chassis.

Questions about this item

What limits GPU length when I install a long card in this XT M3?

The case allows graphics cards up to 430 mm, so any longer model will hit the front panel or bottom fan mounts before it seats fully.

How loud and hot does the chassis get during an all-day gaming session with the three pre-installed 120 mm DRGB fans running?

The included M25 120 mm fans move ample air through the mesh front and bottom; noise stays moderate at typical speeds and thermals remain controlled for sustained loads.

Which motherboards and power supplies must I already own for this Micro-ATX case to work?

It fits Micro-ATX or Mini-ITX boards including rear-connector designs such as MSI Project Zero, ASUS BTF and Gigabyte Project Stealth, and accepts PSUs up to 150 mm long.
