This Gamdias brand casing is completely new. I am going to sell my PC, that's why the casing is being sold. The power button of the casing does not work. I live in Kuakata, so a brother at a local computer servicing shop here told me to change the button. He gave me a motherboard on/off button like a wire, which is directly attached to the motherboard. The PC is currently being run with that. The power supply is an original Value Top installed.
