Changed the backlight. Now a pure green glow. Once again I pressed the controller button (displayed on the top wall) - now the backlight is red. With its pros: Appearance of the system unit after assembly. Installed fans inside the case. A place for the power supply and a way of breeding wires inside the case. Special insert with LED strip between the body parts. Button backlight control. Has some cons: For now - one of the best deals for a bright gaming computer home.
