sid, this is the submersive cooling i was going on about, and after extensive research, i've concluded it really isnt a viable option
1) the best oils for the job would literally cost £100's to fill a tank
2) other oils which might seem to do the job are actually slowly disintegrating into more harmful chemicals which are capable of damaging your parts
3) the oils will also disintegrate the tank
4) a little heavy for carry around to lan parties
5) still cant submerge hdd's and cd drives which in my case are the loudest part of my pc
6) cleaning up is gona be a hastle, and the better quality the oil, the harder it is to clean.
7) any modifications mean cleaning the components involved first.
