I've finished a first build with a "Fractal Design Focus G" case which features a clear acrylic side panel. Everything is working very well so far, but I've noticed my hand and arm hairs are getting up when I move them near the side panel, which I assume is electricity buildup. This is only happening in the acrylic area, nothing happens on the rest of the metallic chassis. I'm not feeling any shocks when I touch the chassis, IO shield, PSU or some other metallic piece. Is this supposed to happen?
