The machine was heavily loaded with drives when it started acting up, 
now that I've swapped some of them into another box it's running fine 
at the moment. I expect the low voltage would be more of an issue as 
the box was more heavily loaded.

Unfortunately, there don't seem to be any sensors on the board :x

I got a dummy load from maplin and checked with a decent consumer 
multimeter - I'm not really up for poking probes onto the MB.

Indeed, but much less learning involved...
