I am planning to build a new pc but there are a lot of mixed messages like its a waste of money and it is no joke. So is it necessary also i am a first time builder if that helps. I am planning to get one anyways as it costs 3 bucks and i can reuse it but i am confused as to how to be grounded. If it does matter could you please tell me how to stay grounded. I have heard people talk a bout attaching it to the case or the psu but wont attaching it to the psu be a problem seeing as you have to put it in the case eventually. I have also heard a bout just putting it into the grounding outlet which one is best and does it even matter. THANKS
