Then unscrewed the screws around the harddrive, then unplugged all the power cable, do the same to the power supply and slowly pull it away. After that, unscrewed all the screws around the motherboard, remove the safety pin and slowly took away the CPU (The CPU is extremely important please be careful). At last, pull away the motherboard.
