The fluorinert coolant was really neat stuff too. Inert, so you could submerge electronics in it to cool them. I was able to find recycled coolant and used that to do the liquid cooled build for my dual celeron system where coolant flowed over the board/cpu. Knowing what I do now... I should have been far less cavalier with the stuff.
