One sort of unrelated data point - a lot of the connectors in a typical PC are
not fused in any way (video card, hard drives, even MB).
Many years ago when I was doing support, one of the computers in the lab would
power on. Doing some debugging, I pulled one of the hard drives and the user
asked me how I know it was that hard drive. My answer was that I could see see
smoke coming off its circuit board.
It just seems to me that there are potentially a large number of ways anything
powered by a computer PS could go up in smoke, so I'm not sure why one should be
more concerned about the HDPVR vs a hard drive or other component.
