The Tower 300 Limestone Micro Tower Chassis
The Legacy Continues
As a new edition of The Tower Series, The Tower 300 Limestone 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 Limestone 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 Limestone 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.
