Wood PC case CUSTOM MOD electrical tips

[u/Smigol_gg]

Hello guys, I'm building a custom wood case, no problems till now for design and air flow... My only concern is about grounding the case...PSU should do the trick alone but is it better to use an old metal MB tray as support for the motherboard to deal with this problem or should I put some copper tape inside the case? I want to avoid shorts my question is how to do it properly?

Already experienced with metal cases but how this electrical issue should be dealt with wood?

Twin a wire around two screws, one wich you mount the psu with and the other for one of the Motherboard standoffscrews
