Translucent Galaxy
Clarity defines the experience. TG3 is shaped around a layered design philosophy, where structure, light, and space come together to create a build that feels deliberate and visually refined. Framed by high-quality tempered glass, every detail is revealed with precision, enhancing depth, reflection, and the overall sense of presence.
 
Tiered ARGB PSU Shroud
Designed with a stepped structure, the PSU shroud adds dimensional depth to the interior, while ARGB lighting strips trace it to elevate visual impact. Ventilated paneling improves airflow and support for additional fan mounting to further enhance cooling performance.
 
 
Advanced Cooling System
Built for optimized heat dissipation, TG3 features a pre-installed MONTECH GF360 U REV side intake and GF120 U rear exhaust to establish a powerful cooling foundation. The GF360 U REV’s single-frame design simplifies cable management while reducing resonance effect for smoother, more stable operation. With support for up to 9 fans, TG3 offers the flexibility to scale cooling performance for demanding systems.

 

 

 
Future-Proof GPU Compatibility
With generous clearance and optimized airflow, TG3 accommodates today’s flagship GPUs and future high-performance designs with ease, maintaining thermal stability while expanded PSU support provides greater flexibility across build configurations.
Ready for Any Setup
TG3 supports standard ATX, Micro-ATX, and Mini-ITX motherboards, along with rear-connect motherboards such as GIGABYTE Project STEALTH, ASUS BTF, and MSI Project Zero.
 
Showcase Surface for Personalized Builds
The tiered bottom design opens up extra room to highlight your personalization—offering the space and freedom to show off your style.
