Most of us consider the pins to be part of the "harness issue" and its good that you can see oxidation(makes it easy to be fairly confident of what the trouble is). The rack version is very easy to work on and you can always leave out most of the screws for faster access next time(put the extras in a little bag and tape to the inside or rear of the case). I also had a firewire cable fail(why I mentioned it) for no reason(it was only a few months old and had been unplugged and replugged maybe 2 times). +1 for Deoxit
