Description
The FSP CST351 redefines the Small Form Factor (SFF) experience by balancing a compact footprint with high-end thermal capabilities. Constructed from 0.8mm SPCC steel, this Mini-ITX chassis supports up to seven fans and dual 240mm radiators, ensuring that even the most demanding CPUs and GPUs remain cool under load. With a modern I/O featuring USB 3.1 Gen2 Type-C and pre-installed ARGB fans, it provides a premium foundation for enthusiast-grade builds without the bulk of a traditional mid-tower.
This product is for:
- SFF Enthusiasts: Builders looking for a sub-22L chassis that doesn't compromise on cooling or component compatibility.
- Competitive Gamers: Users requiring high-performance GPUs up to 336mm in length for high-frame-rate gaming.

Building in the FSP CST351 is a streamlined process thanks to its optimized internal layout. The 0.8mm thick steel panels provide a rigid, premium feel that minimizes vibration and noise. Thermal management is a standout feature; the ability to mount 240mm radiators at both the top and bottom allows for sophisticated custom loops or dual-AIO configurations. The front-mounted ARGB fans and bottom ambient lighting create a cohesive visual identity that is easily controlled, while the high-speed Type-C port ensures modern peripheral compatibility.
Compared to standard ITX cases like the Cooler Master NR200, the FSP CST351 offers a more aggressive airflow design with its pre-installed dual 120mm front ARGB fans. While many SFF cases struggle with GPU length, the CST351’s 336mm clearance rivals larger Micro-ATX towers, allowing for high-end RTX 40-series cards. Its use of 0.8mm SPCC steel provides superior structural integrity compared to budget SFF alternatives that often use thinner 0.6mm materials.
