This article covers COOLER MASTER Cooler Master TD300 Mesh ミニタワーPCケース TD300-KGNN-S00 ブラック CS8325.

Overview

Cooler Master's MasterBox TD300 Mesh is a compact mini-tower PC case featuring a distinctive polygon mesh front panel. The diamond-inspired three-dimensional mesh offers excellent airflow while acting as a dust filter, balancing performance and aesthetics. It supports Micro ATX and Mini ITX motherboards, making it an ideal choice for space-conscious builders who don't want to compromise on expandability. The case comes pre-installed with two 120mm PWM ARGB fans, delivering both effective cooling and customizable lighting out of the box.

Compatibility Guide

The TD300 Mesh is designed for Micro ATX and Mini ITX motherboards; standard ATX boards are not supported. The power supply mounts at the bottom, supporting units up to 140mm in length. Graphics card clearance is generous at 344mm (with front fans), enough for most modern high-end GPUs. CPU cooler height maxes out at 166mm, allowing for large air coolers or AIO liquid cooling. The removable top panel simplifies installation and maintenance, a thoughtful touch for builders who frequently tinker with their system.

Product Info

Launched in November 2021, the MasterBox TD300 Mesh sits in the mid-range price bracket, typically around $80-100 USD. It can accommodate up to six 120mm fans, and supports radiators of 240mm/280mm in front, 240mm on top, and 120mm in the rear. Storage options include two 2.5-inch drives and one 3.5-inch bay (convertible to 2.5-inch). The side panel is tempered glass, showcasing the internal components. The front polygon mesh is both a design statement and a functional air filter.

Best Use Cases

This case is perfect for gamers building a compact yet powerful Micro ATX system. The ARGB fans add flair without needing extra purchases, making it a great choice for first-time builders. Its effective dust-filtering mesh also suits users in dusty environments. The ample radiator support appeals to enthusiasts who want to run a custom water loop or a high-performance AIO cooler in a small form factor. Additionally, the clean internal layout works well for a home theater PC or a quiet workstation.

Things to Consider

Be aware that this case does not support ATX motherboards, so if you already own an ATX board, look elsewhere. When installing a top-mounted radiator, check for clearance with tall RAM modules or motherboard VRM heatsinks. Cable management space is tight; a modular PSU and zip ties are recommended for a tidy build. The 140mm PSU length limit might restrict your choice of high-wattage power supplies. Despite these caveats, the TD300 Mesh offers excellent airflow and build quality for its size and price. ## Alternatives
Main competitors include the Fractal Design Define Mini C and Cooler Master's own NR400. The Define Mini C prioritizes acoustics with sound-dampening panels, making it better for silent builds. The TD300 Mesh counters with superior airflow and ARGB lighting out of the box, appealing to gamers who want both performance and visual flair. The NR400 offers an external 5.25-inch drive bay, but the TD300 Mesh has a more modern design and better expandability for water cooling.
