The Legacy Continues
As a new edition of The Tower Series, The Tower 300 inherits the classic vertical case design but comes in an octagonal prism shape. It has amazing hardware compatibility, accommodating a 4090 GPU, a standard-sized power supply up to 220mm, and a 420mm AIO radiator. What’s more, it can accommodate up to eight 120mm/140mm fans on the top, back, PSU cover and right side fan bracket. If you want to make The Tower 300 more visually appealing, you can purchase the separately sold 3.9″ LCD Screen Kit and Chassis Stand Kit to upgrade the build; the former to display real-time component information and the latter for a unique view with a special horizontal placement.

Classic Vertical Body Design
The Tower 300 retains the iconic contours of its predecessors, with a vertical body design but in an octagonal prism shape, allowing the chassis to have a smaller footprint and providing flexibility and minimizing obstructions to your gaming and workspace.
A Unique View – Horizontal Case Placement
With the optional chassis stand kit, which includes a bottom cover panel and a display stand for horizontal case placement, The Tower 300 allows for easy customization of the case for a unique viewing experience.
How to install:
1. Unscrew the original feet located on the base of the chassis
2. Install the new bottom cover of the chassis and carefully place The Tower 300 on the stand
*Note: It is recommended to position the radiator higher than the AIO pump.
Supports up to a 420mm Radiator on the Right
The Tower 300 delivers exceptional cooling that it supports up to a 420mm radiator on the right side, which effectively reduces the temperature inside the chassis and maintains optimal system performance.
Tool Free Panels for Easy Access
The Tower 300 features three 3mm tempered glass panels on the front and two perforated panels on each side. All are easily removable without tools.
Two CT140 PC Cooling Fans Pre-installed
The Tower 300 features two 140mm PWM fans on the top to provide good cooling performance.

Unify your fans with your build!
Thermaltake launches brand-new CT series fans, allowing users to choose from black or white, RGB or non-RGB, to match whatever color scheme you have.
