Multimedia Computer Trainer/Case 

• It is very important to know how you are dealing with trainers before something goes wrong and someone can be badly injured. Computer case basically contains the such as the motherboard and circuit board, wires, connectors, data cables, CPU, power supply. You should take ESD (Electrostatic Discharge) precautions. We connect wires to the computer and keyboard to power on.
