Montech AIR 903 MAX počítačová skříň Midi Tower, tvrzené sklo, barva: bílá

Montech AIR 903 MAX Midi Tower White is a mid-tower PC case designed for high airflow and broad hardware compatibility. The front metal panel provides large-area ventilation and the case ships with three pre-installed 140 mm PWM front fans plus one 140 mm rear fan. It supports ATX and E-ATX motherboards, multiple storage options (2 x 3.5" and 5 x 2.5" bays), and accommodates long and wide graphics cards, while offering a bottom-mounted power supply layout and a side window for component visibility.

Advantages

The AIR 903 MAX features a front panel with approximately 51% ventilation area to maximize airflow, removable dust filters with a quick-release design for easy cleaning, and pre-installed HP140 PWM fans that balance low noise and cooling performance. It supports up to nine fans, front and top 360 mm AIO radiators, and provides 27 mm of cable routing space with rubber grommets and Velcro straps for tidy cable management. The case accepts GPUs up to 400 mm in length and 190 mm in width and offers E-ATX and SSI-EEB compatibility with pre-punched mounting and cable routing holes.

Suitable for

• Gaming PC builds requiring strong cooling and large GPUs

How to use

Install the motherboard on the pre-punched standoffs and route power and data cables through the provided cable holes and the 27 mm cable channel. Mount storage drives in the dedicated 3.5" or 2.5" bays and install the GPU, noting the generous clearance for long cards; optionally use a vertical GPU mount (sold separately) after removing the seven PCIe slot covers. Fit AIO radiators at the front or top up to 360 mm, and confirm fan orientation to maintain front-to-back airflow. Use the quick-release dust filters for regular cleaning.

Recommendations

For best thermal results, maintain a front-to-back airflow configuration, keep the dust filters clean, and choose PWM-controlled fans or a compatible fan hub to optimize noise versus cooling performance. When installing very wide GPUs, verify clearance with installed cables and cooling solutions.
