I'm not trying to piss-off the pope here, but I don't agree. I have heard and seen this discounted too many times as a myth... (although I guess that could depend on what you call a large amount).

3. Does distilled water leach minerals from my body?
No, that is not an accurate statement. Distilled water is the purest form of water, the universal solvent. Pure water does absorb discarded minerals and with the assistance of the blood and lymph(mostly water), transports them to the kidneys for elimination. It is this kind of mineral elimination that is incorrectly referred to as 'leaching'. The expression that distilled water leaches minerals from the body is inaccurate. Distilled water does not leach out body minerals, it collects and removes minerals which have been rejected by the cells and tissues, which if not evacuated, can cause arterial obstruction, arthritic deposits and other potentially serious bodily damage.
This quote is referring to distilled water but the same holds true for DI water because it isn't DI by the time it gets poured into a glass and drunk...

DI will do the same thing to a water-cooling system by drawing metal from any aluminum, copper, etc. present. Such a small amount of water will not draw out enough metal to make a perceptable difference in the structure of your components, but it *will* cause the DI to increase its ion content, and thus its conductivity and ability to function as an electrolyte in a galvanic cell, such that it will protect your system no better than distilled water.

Agreed...
DI water is OK to use in a PC water-cooling system because it's a one time fill up and not a continuously filling process. By the time the DI water makes one pass thru the system it will have absorbed enough ions from surface contact and dissolve gases to be very far from deionized! So unless you have "free" access to DI water it doesn't make much sense to spend the extra money and isn't any better than good distilled water.
IMHO one of the best sources for PC water coolant is the grocery store - look for a brand of distilled water that has been RO (reverse osmossis) filtered, steam distilled and ozonated.
