In the vast computer wasteland known as San Antonio, Tx, where anything more exotic than a 20gb hard drive virtually unheard of, I have foundan automotive shop that has TWO bottles of Purple Ice! Until now, I had yet to find a *local* source for ANY of the recommended (or popular) additives used in a watercooled PC.
I think that using Purple Ice will pull my watercooling adventure into the realm of understandability where my wife is concerned because her favorite color is purple (at least that's the argument that I'm going to use).
"Yeah honey, I know I spent a lot of money, but look at the tubes! They're full of purple water, and that's your favorite color!"
