Montech has launched the TG3, a new ATX mid-tower PC case designed for users building gaming PCs and performance-focused systems on a budget. The new case features a pillarless front-left corner design with dual tempered glass panels covering the front and left sides, giving builders a clear view of their components.


The TG3 uses a horizontally separated internal layout, keeping the power supply area isolated from the main hardware section. Unlike many dual-chamber cases, Montech does not place a 3.5-inch drive cage in the lower area. Instead, the bottom compartment is reserved for the PSU, which is positioned toward the rear of the case.
Key features of the Montech TG3 include:
- Dual tempered glass front and side panels with a pillarless corner design
- ATX mid-tower form factor for gaming and workstation builds
- Support for graphics cards up to 43 cm in length
- CPU cooler clearance of up to 18 cm
- PSU supports up to 25 cm in length
- Pre-installed ARGB fans included in the package
- Compatibility with some backside-connector motherboard designs
- Available in black and white color options
The black version of the TG3 includes a metallic silver finish on the lower PSU section, while both color variants feature an LED diffuser that adds additional lighting effects. The motherboard tray includes cable management cutouts that allow compatibility with certain rear-connector motherboard layouts, although Montech has not officially highlighted this as a main selling point.
Cooling is handled by two included ARGB fans. The side-mounted fan position comes with the GF360 U REV, a 360 mm x 120 mm compound fan, while the rear exhaust uses the GF120 U 120 mm fan. Both fans feature ARGB lighting integrated into the fan blades, allowing users to match their system lighting setup.


With dimensions of 465 mm x 239 mm x 523 mm, the TG3 provides enough room for modern components while keeping the overall footprint suitable for most desk setups. The case can accommodate long graphics cards and large CPU coolers, making it suitable for current gaming hardware.
The Montech TG3 is now available, with the black model priced at $60 and the white version listed at $80. The case combines a glass-focused design, including RGB cooling, and support for large components, targeting PC builders who want a modern chassis without a high price tag.
