I am going to buy an anti-static wrist strap for a new build I am doing next Wednesday. My case is the Cooler Master MasterCase 5 and my PSU is an EVGA SuperNOVA 750 Watt. Those are both black and I assume they are painted. When I am building, what should I ground myself with? The case and PSU are not bare metal and the inside of the case is also black and painted, what should I clip myself to so that I am always grounded? Please help, all threads I have found just say PSU or case.
