It's already turned on on that picture Still sounds like a freight-train. However, I've now taped the hdd to the graphics card, so that they now share the gpu's fan for cooling. I think it's a pretty decent solution There's no vibration at all now, but there's still a strange sound coming from somewhere.. I tried opening the power-supply up while the computer was running to see if there were anything strange going. Except for some static discharges I found nothing out of the ordinary.. I'm beginning to think that there's something inside the hdd that's not working as intended..
