The Legacy Continues

As the newest edition of the Tower Series, the Tower 300 inherited the classic vertical design but was updated with a new octagonal prism shape to meet todays aesthetics. It may be small but it sure can pack a punch with support for up to 400mm GPUs, 420mm AIOs, and up to a 220mm PSU. If cooling is a concern then the Tower 300 has you covered with being able to accommodate up to eight 120mm or 140mm fans. Also did someone say upgrades, well the Tower 300 has optional 3.9 LCD screen kits as well as Horizontal Chassis stands sold separately so your build comes out exactly how you want it to.



Classic Vertical Body Design

The Tower series has been iconic for its vertical body designs and the Tower 300 follows in those footsteps. However, with its new octagonal prism design we were able to not only increase the viewing areas for the components inside but also allow for better airflow and bigger cooling options too. This gives the Tower 300 the classic looks of its predecessors but with even better performance and updated styling.



A Unique View

Our optional Horizontal Chassis Stand Kit comes not only with the stand itself but also included is a replacement bottom cover to delete the feet and provide a clean look.

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.



Maximum Radiator Support

Supporting up to a 420mm AIO radiator on the right side of the case the Tower 300 is ready for some of the most demanding hardware. And to assist that AIO with optimal chassis temperature is the ability to mount up to eight 120mm or 140mm fans.P/N
