I will follow your suggested testing for the tv card, and see if it makes a
difference.  It is really my only concern here.

I was planning on submerging the PSU as well.  This was again based on what
the original link I posted showed.  Again, to take it slowly, I might start
with just the motherboard and 1 tv card in the oil, see how it goes, if it
all works, then I can try with the PSU, then the rest of the tv cards.

The sourcing of the oil in Australia seems to be the biggest hurdle, as it
does need to be impurity free as you mention.
