This Gamdias brand casing is completely new. I am going to sell my PC, so 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 an on/off button like a wire for a motherboard, which is directly attached to the motherboard. The PC is now operated with that. The original power supply of Value Top is installed.
