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.

Left and Right 4mm Thick Tempered Glass Window Design

Premium-quality 4mm thick tempered glass guarantees the durability of the window; moreover, the two-panel tempered glass design permits users to admire their system from either left side or right side.

Fully Modular Concept

The fully modular drive brackets provide the ease of installation/removal and maximize the interior space for custom cooling loop. Especially, the tool-less drive bay design allows users to freely interchange the 3.5” and 2.5” hard-drives to suit their particular needs.

Power Supply Cover For A Clean Build

Designed for advanced cable management, the pre-mounted PSU shroud allows the entire bottom area of the case to be used to reorganize unused cables.

Excellent Expandability

The Core G21 TG features its roomy installation space for high-end PC hardware. It supports a tower CPU cooler with maximum height 160mm, and a dual expansion slot VGA of up to 410mm in length. Moreover, it has the ability to accommodate multiple 3.5”/2.5” storage devices.

Superior Cooling Capability
