So i shook my pc and there was a rattling noise or something or a clicking my pc was off btw and when i moved it forward the case doesn’t move as much and the sound stopped and sometimes regardless of it being being where it was originally and where i moved it to the sound happens again, ive taken some components out like my harddrive and ssd and moved some wires around and the noise is still there is it just my case or is it one of my components doing it im very concerned
