A mid-tower chassis offers full assembly capacity and expandability for enthusiasts to create massive liquid cooling systems

Thermaltake Core X31 Mid Tower Chassis

The Core X31 features outstanding cooling performance with compatibility for liquid cooling components. With its unprecedented space for high-end hardware and liquid cooling expansion, the Core X31supports the latest ATX, Micro ATX, Mini-ITX motherboards, and all high-end GPU cards. Moreover, the Core X31’s integrated power cover helps tidy the entire bottom area by allowing users to easily organize unused cables, and in return provide the maximum interior space needed for advance cooling performance or liquid system build.

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.

Power Cover Design

Power supply placement design is one of the Core X31 unique features. The entire bottom area can be used to reorganize unused cables, which makes for a tidy-looking system. Users can enjoy the freedom of gaining the maximum interior space for advance cooling performance or liquid system build. Furthermore, the PSU cover can hold two additional 2.5” HDD drive bays.

Fully Modular Concept

A “2 + 3” drive bay design for storage devices makes setting up the latest storage solution super easy and flexible. Besides hanging 3 x 3.5”/2.5” at the back of motherboard tray, users are capable of freely adjusting the 3.5” hard-drive cage to suit their particular needs.

Dust Reduction

Super-fine fan filters provide excellent protection and minimize dirt and dust on the top, inside the front-side panel, and at the bottom. A magnetic fan filter on the top makes it super easy to attach the filter for dust filtration.

Advanced Ventilation

Featuring a width of 250mm, the Core X31 enables users to build a complete high-end system that supports up to triple 120mm, double 140mm liquid cooling radiators or up to 200mm case fans. With extended graphic card support, the Core X31 protects the hardware while increasing the CPU’s overclocking potential for users looking to get the most out of their hardware.

Remarkable Expansion

The Core X31’s modular drive racks allow gamers to easily install up to seven data storage devices, a dual expansion slot VGA of up to 420mm in length, and a tower CPU cooler as high as 180mm. Even with a high-wattage PSU stretching to 220mm in length, the Core X31 gains more for custom cooling components to freely interchange HDD cage sections for maximum cable management space with adjustable drive racks.
