Montech AIR 903 MAX Midi-Tower Case with window and RGB lighting, Black

The Montech AIR 903 MAX is a mid-tower chassis designed for thermal performance, featuring a full mesh front panel for high-volume airflow. It comes equipped with four pre-installed 140mm PWM fans; three ARGB fans are mounted at the front for intake, while a non-illuminated fan serves as the rear exhaust. This cooling configuration is intended to support demanding hardware configurations. A tempered glass side panel provides a clear view of the internal components and any installed lighting.

This case accommodates a wide range of hardware, with support for motherboards from Mini-ITX up to the E-ATX form factor. It provides generous internal clearances for large components, including CPU air coolers up to 180mm in height and power supplies up to 240mm in length. Liquid cooling options are extensive, with mounting locations for 360mm radiators at both the front and top of the chassis. The front I/O panel includes one USB Type-C port, two USB 3.2 Type-A ports, a combo audio jack, and a dedicated ARGB control button.
