## Long description

Montech AIR 903 is a mid-tower PC case designed for users who need high airflow, extensive hardware compatibility and easy maintenance. The case features a metal front panel with 51% ventilation, pre-installed three 140mm PWM fans, dust filters and generous internal space to support large GPUs, multiple radiators and E-ATX motherboards.
Advantages
The AIR 903 emphasizes cooling efficiency and versatility: its highly ventilated front panel and included HP140 fans provide strong airflow while remaining relatively quiet under varied loads. Removable filters and a quick-release design simplify cleaning and dust management. The layout supports up to nine fans, front and top 360mm AIO radiators, tall CPU air coolers and vertical GPU mounting for improved thermals and presentation. Cable management features include a 27mm routing channel, rubber grommets and Velcro straps to keep the interior tidy during builds.
Key specifications
Form factor support: E-ATX, ATX, Micro-ATX, Mini-ITX, SSI-EEB
Front panel ventilation: 51% metal mesh
Pre-installed fans: 3 × 140mm PWM (HP140)
Maximum GPU clearance: up to 400 mm length, up to 190 mm width
Radiator support: up to 360mm front and top
Maximum fans supported: up to 9 fans
CPU cooler clearance: generous tower cooler support (model-dependent)
Cable routing space: 27 mm with rubber grommets and Velcro straps
Vertical GPU mounting: supported (mounting kit sold separately)
How to use
Install the motherboard according to its form factor using the pre-punched mounting holes, route cables through the 27mm channel and secure them with the provided Velcro straps and rubber grommets. Fit storage drives and the power supply in their designated bays, then mount the graphics card — up to 400 mm in length — in the standard or vertical orientation if using the separate vertical GPU kit. For liquid cooling, install up to 360mm radiators at the front or top, and position the three pre-installed 140mm PWM fans or add additional fans as required to optimize airflow. Clean dust filters regularly using the quick-release access to maintain thermal performance.
Recommendations
For optimal cooling, use a combination of front intake and top/exhaust fans, keep dust filters clean, and check GPU width before purchase if using large triple-fan graphics cards. Purchase the Montech vertical GPU mounting kit separately if you plan to mount the graphics card vertically.
