PC Case Thermaltake Divider 300 TG Midi Tower Black

The Thermaltake Divider 300 TG is an ATX mid-tower chassis with two 3mm tempered glass windows at the front and left side and one preinstalled 120mm rear exhaust fan. The case combines an open-frame inspired layout with removable triangular steel-and-glass panels, a ventilated PSU cover, riser GPU support bracket and rotational PCI-E slots for flexible GPU orientation. It supports various cooling configurations and common motherboard sizes for mainstream and enthusiast builds.

Advantages

The Divider 300 TG offers tool-free removable tempered glass panels for easy component viewing and access, thicker 3mm glass for improved scratch resistance, and a ventilated PSU cover that helps hide cables while improving airflow. The included riser GPU support bracket reduces GPU sag and load on PCI-E slots, while magnetic and removable dust filters on top, right inner side and base simplify maintenance. Rotational PCI-E slots allow horizontal or vertical GPU display to suit different builds.

Suitable for

• Mainstream and enthusiast gaming PC builds
• Compact ATX, Micro-ATX and Mini-ITX systems
• Systems requiring vertical GPU display or custom aesthetics
• Air-cooled or AIO liquid-cooled configurations

How to use

Install a compatible ATX, Micro-ATX or Mini-ITX motherboard and route power and data cables under the ventilated PSU cover to improve airflow and cable management. Mount storage drives into the dedicated 3.5" or 2.5" cages and secure the GPU using the included riser support bracket; choose horizontal or vertical GPU mounting with the rotational PCI-E slots as needed. Remove the triangular tempered glass panels without tools to access components or show the build, and install additional fans or AIO radiators according to the listed compatibility to achieve the desired cooling.

Recommendations

Use the magnetic filters on top, right side and base and clean them regularly to maintain optimal airflow. When installing long GPUs or AIO radiators, verify clearance against the listed maximums (GPU length 390 mm, CPU cooler height 145 mm, PSU length 220 mm) and consider removing one tempered glass panel temporarily for improved intake if front ventilation is restricted.
