Tt LCS Certified

Tt LCS Certified is a Thermaltake exclusive certification applied to only products that pass the design and hardcore enthusiasts standards that a true LCS chassis should be held to. The Tt LCS certification was created so that we at Thermaltake can designate to all power users which chassis have been tested to be best compatible with extreme liquid cooling configurations to ensure you get the best performance from the best features and fitment.


Advanced Ventilation

The Level 20 GT gives users the option to build either a complete high-end air or liquid cooled system, with extensive support for either.

The GT comes with one 140mm fan installed, but has space for up to 8 case fans, as well as support from 120mm all the way up to 420mm radiators. Intake areas are also protected by removable dust filters, installed in the front, top and bottom of the case to shield your hardware from particles in the air.

Superior Hardware and Liquid Cooling Support

The Level 20 GT supports up to E-ATX motherboards, CPU coolers up to 200mm in height, VGA lengths up to 310mm and PSU sizes up to 220mm in length. On top of this, the GT is also fully capable of housing a complete liquid cooling system, including our range of PR-22 pumps and RGB Plus hardware.

Patented Rotational PCI-E Slot Design

Our brand new patented rotational PCI-E system allows you to stack multiple GPUs either vertically or horizontally, depending on how you want to build your system.

Vertical Radiator Placement

Whether you're building a custom loop or running an AIO CPU cooler, the Level 20 GT lets you mount your radiator against the back panel to show off your RGB fans. The back panel provides adequate exhaust while putting your RGB fans on display, with support for up to a 420mm radiator as well as radiator support on the front and top of the chassis.

Power Cover Design

Level 20 GT is designed with a removable power cover, which can be used to organize unused cables to make for a tidy-looking system.

Four Tempered Glass Panels

The Level 20 GT boasts tempered glass panels on the front, top and both sides. The left and right hinged doors are also equipped with smart lock security systems to secure the inner components of your case.
