Phanteks XT M3 RGB Micro Tower musta

The Phanteks XT M3 RGB Micro Tower Black is a compact microATX gaming chassis designed for efficient cooling and neat cable management. The case supports Mini-ITX and microATX motherboards, accommodates 2.5" and 3.5" drives, and offers multiple fan and radiator mounting positions including a dedicated top area for a 360 mm radiator and triple 120 mm fan mounts at the bottom for direct GPU airflow. Its black tempered glass side panel provides a clear view of internal components while maintaining a streamlined exterior.

Advantages

The case supports up to nine 120 mm fans and ships with two 140 mm front fans and a 120 mm rear fan for balanced airflow.

How to use

Install a Mini-ITX or microATX motherboard on the standoffs, route cables through the dedicated channels behind the motherboard tray, and secure storage drives in the appropriate 2.5" or 3.5" bays. Mount cooling fans in the front, top, rear, or bottom locations depending on your cooling layout; install a 360 mm radiator in the top if using an AIO cooler. Connect front-panel USB and power headers to the motherboard and secure the tempered glass panel after completing component installation.

Recommendations

For best thermal performance, combine the included front 140 mm fans with additional 120 mm fans in the bottom and top positions to create a balanced airflow path: intake at the front and bottom, exhaust through the top and rear. Ensure cables are routed cleanly to maintain unobstructed airflow and visibility through the tempered glass panel.
