Panoramic ATX Mid-Tower for Showcase Builds

The Montech TG3 Black is an ATX mid-tower case designed for builders who want a panoramic view of their components. It supports ATX, Micro-ATX, and Mini-ITX motherboards, including back-connect designs for cleaner cable routing. A tiered interior platform provides dedicated space for displaying collectibles or custom accents. The black SPCC and tempered glass construction creates a refined, translucent aesthetic.

Pre-Installed Unibody Fans Reduce Cable Clutter

Installation is simplified by a pre-installed 360mm ARGB unibody side intake fan and a 120mm ARGB rear exhaust fan. The single-frame design minimizes vibration and reduces the number of cables needed for fan power and lighting. Builders should verify clearance for the side-mounted 360mm fan against tall motherboard heatsinks or large CPU coolers. The bottom dust filter is removable for maintenance access.

Supports RTX 5090 Class GPUs and 360mm Radiators

The spacious interior accommodates graphics cards up to the RTX 5090 class, ensuring compatibility with flagship models. Radiator support includes up to 360mm at the top, 240mm on the side, and 120mm at the rear for liquid cooling flexibility. Seven expansion slots provide room for thick graphics cards and additional add-in cards. Front I/O includes USB 3.0, Type-C, and a headset audio jack.

Questions about this item

How do I confirm the pre-installed GF360 U REV and GF120 U ARGB fans are spinning and lit after I power on the build?

Power the system and watch the side 360mm intake fan and rear 120mm exhaust fan; both should rotate and display ARGB lighting immediately, confirming the unibody fans are working.

Which fans, radiators and drive brackets come in the box, and what must I purchase separately?

The case includes one 360mm side ARGB unibody fan and one 120mm rear ARGB fan; supports top 360mm, side 240mm and rear 120mm radiators; provides one 3.5" and two 2.5" drive bays; PSU is not included.

Should I choose the ATX, Micro-ATX or Mini-ITX motherboard layout for this TG3 Black case?

All three form factors fit, including back-connect designs such as ASUS BTF, MSI Project Zero and GIGABYTE Project STEALTH; pick the board size that matches your CPU and feature needs.
