The tempered glass front and side panel give the TG4 RGB its stylish gaming look, and the hardware can be marveled behind its showcase. The LED fans provide an atmospheric illumination for the installed components, while the side air-inlets also ensure an adequate intake of air.

The case design of the TG4 RGB is not only straightforwardly minimalist. It is also consciously designed to be as compact as possible, while ensuring that there is enough space for common hardware. Graphic cards with a length of up to 37.5 cm can fit into the TG4 as well as CPU coolers with a height of up to 16 cm. Power supplies up to 26.5 cm in length will also find room.

The TG4 RGB offers numerous drive installation options. In total, up to two 3.5-inch drives and up to four SSDs can be installed. All drives can be quickly and easily mounted using slots on the inner side panel or via the hard drive cage on the bottom panel

The TG4 RGB comes pre-installed with three addressable LED fans behind the front panel and another on the rear panel. These can be conveniently and creatively lit in 16.8 million colors via mainboards which have headers for addressable LEDs (pin configuration: 5V-D-coded-G or 5V-D-G). Alternatively, if this mainboard connection is not available, the reset switch of the case can be used to select 14 lighting effects.
