But it is still being used and according to the wiki, it is *highly
refined* mineral oil.  While startpaging around, I found that they
refine it more and remove the bad stuff, PCB's and such, so that it
isn't toxic or anything.  They changed that way back in the 70's or
80's.  The posts from Volker imply that it is not used anymore but it
is.  I posted a link that says it is and a video of how the transformers
are still being made today.  Heck, I even found a company that currently
makes the transformer oil.  If no one is using mineral oil like Volker
implies then why do they still make it? 

Point is, they still use mineral oil in transformers and it serves two
functions.  It removes heat and acts as a insulator.  Both of those are
good things as opposed to water and a computer motherboard.  Spill water
on a mobo, buy a new mobo.  Spill mineral oil on a mobo, just clean up
the mess.  Given the cost of a mobo, CPU, and anything else that could
be ruined, I'd prefer mineral oil over water.  So, I'm still not putting
water in my puter.
