Panoramic ATX Mid-Tower Case

The Montech TG3 White is a panoramic ATX mid-tower case with dual tempered-glass panels and integrated ARGB lighting. It supports ATX, Micro-ATX and Mini-ITX motherboards including back-connect designs. A tiered interior platform provides dedicated space for displaying collectibles or custom accents. The chassis arrives without a power supply and mounts the PSU at the bottom.

Pre-installed 360mm ARGB Unibody Fan

The case includes a single-frame 360 mm side intake fan and a 120 mm rear exhaust fan, both ARGB. This unibody design reduces cable clutter and vibration compared to traditional multi-fan stacks. Radiator support reaches 360 mm at the top, 240 mm on the side and 120 mm at the rear. The layout clears graphics cards up to 430 mm and CPU coolers up to 180 mm.

Front USB Type-C and Display Platform

Front I/O offers two USB 3.0 ports, one Type-C port and a headset audio jack. Internal drive capacity covers one 3.5 inch bay and two 2.5 inch bays. Seven expansion slots accommodate full-length add-in cards. Ventilated panels and room for up to nine fans give builders flexible airflow options for high-performance components including RTX 5090-class GPUs.

Questions about this item

Will a 430 mm graphics card and a 250 mm power supply fit in the Montech TG3 White?

The case supports graphics cards up to 430 mm and power supplies up to 250 mm, so both components will fit within the stated limits.

How are the pre-installed 360 mm side intake and 120 mm rear exhaust fans connected, and what step is often missed?

The unibody fans use a single-frame design with integrated ARGB and PWM cables; the step often missed is plugging the combined 3-pin ARGB header into the motherboard or a controller for lighting control.

What filter maintenance does the TG3 White require over time?

A bottom dust filter is fitted; it should be removed and cleaned periodically to maintain airflow through the ventilated panels and pre-installed fans.
