Cooler Master MasterBox TD300 – Mesh Airflow Micro-ATX Case

About the Cooler Master MasterBox TD300 Mesh

The Cooler Master MasterBox TD300 combines mesh front panel cooling with tempered glass aesthetics in a Micro-ATX form factor. This case is designed for builders who want proper airflow and RGB lighting without spending on features they don't need. Whether you're assembling your first gaming rig or upgrading to a more compact setup, the TD300 handles modern components with room to grow.

What This Case Does for You

The mesh front panel ensures unrestricted airflow to your components, preventing thermal throttling during intense gaming sessions or rendering workloads. Two pre-installed CF120 ARGB fans immediately provide intake cooling, eliminating the need to buy separate fans before your build is operational. The integrated ARGB hub simplifies cable management and RGB synchronization across your components. With support for Micro-ATX and Mini-ITX motherboards, you get four expansion slots for modern GPUs and additional cards. The 344mm GPU clearance accommodates current RTX 50 series graphics cards and previous-generation RTX 40 series models without fitment issues.

Cooling Versatility in Compact Form

Despite its Micro-ATX footprint, the TD300 supports up to 280mm radiators on both the top and front mounting positions. This means you can install serious AIO liquid coolers for high-performance CPUs without upgrading to a larger case. The 166mm CPU cooler clearance accommodates most air coolers, giving you flexibility in your cooling approach. Comprehensive dust filters on the front, top, and bottom panels protect your components while maintaining airflow, reducing maintenance frequency compared to cases with limited filtration.

Perfect For

• First-time builders wanting a complete case with fans and RGB already included for custom PC builds without hidden costs
• Compact gaming setups that need to fit modern GPUs and liquid cooling without taking up excessive desk space
• System upgraders moving from older ATX cases to a cleaner, more efficient Micro-ATX layout with better cable management
• Users prioritizing airflow performance over solid panel aesthetics, especially in warm Singapore climate conditions
