Assembling your PC - Step by Step Guide
• If you have purchased all the necessary hardware your are
ready assemble your PC.
• Before unpacking your components from its original anti-static
bags you must put on your anti-static wrist strap, which will
discharge your self.
• It is important that you discharge yourself or there is a danger
that you can damage your components by anti-static shock by
touching the components.
