With the TG4 RGB ATX Midi Tower, you can showcase your hardware in elegant glass and rich colors. This is ensured by the fully visible front and side panel made of tempered glass, along with four pre-installed 120 mm LED fans. The case design is based on the TG5, but the TG4 RGB is much more compact and is especially suitable for gamers with air-cooled systems. Three addressable LED fans are pre-installed in the front and one in the back of the TG4 RGB. These can be conveniently illuminated in 16.8 million colors via motherboards with a connector for addressable LEDs or in 14 lighting effects via the reset button if the corresponding connector is not available. The tempered glass front and side panel give the TG4 RGB its stylish gaming look, allowing the hardware to be admired like in a showcase.

The LED fans also provide atmospheric illumination of the installed components. Side air intakes ensure sufficient air intake. The case design of the TG4 RGB avoids unnecessary external features and is deliberately designed to be as compact as possible while ensuring enough space for common hardware. Graphics cards with a length of up to 37.5 cm fit into the TG4 RGB, as do CPU coolers up to 16 cm high and power supplies up to 26.5 cm long. The TG4 RGB offers numerous installation options for drives, accommodating up to two 3.5-inch drives and up to four SSDs. All hard drives are quickly and easily mounted using holes in the inner side panel and the hard drive cage on the bottom of the case. Numerous cable passages in the inner side panel ensure that cables remain out of sight. To prevent the TG4 RGB from getting dirty, two removable dust filters are placed on the sides behind the front, complemented by another one on the bottom of the case.
