Hey guys, I have a NZXT guardian 921B case and I am rewiring some of my stuff and would like to wear an anti static wriststrap to be safe while doing this. I realized that when I built this PC I didn't use it correctly but lucked out and didn't shock anything. My problem is that there's no unpainted part of the case that I can connect it to. There's unpainted screws but they are too small. I was also told that you are not supposed to connect the PSU in while doing this. The only place I thought might work would be the outside of my GPU and connect it to one of the DVI screw holes.
