Yeah, I mean, using distilled isn't bad..but discolouration of the water is just gonna happen. Yet I always see people mention they distilled is their coolant of choice...to me, it's a high-maintanence fluid. The only issue with that is that some stuff the coolant picks up is going to affect cooling ability, and sometimes, say if there was a pile af gunk in one spot, using distilled may spread it over the entire loop. Personally, I just use tap water. Every six months, blocks get pulled, and they get CLR'd. I understand the whole kid thing...but hte only pets I got are fish! and no..my typing sucks becuase my keyboard cannot hadle how fast I type. It's better than the last one... I had shoulder surgery again back a few months ago, and jsut got use of my arm back a coupel of weeks ago...I had been typing with one hand for like 6 months, which slowed me down a fair bit. NOw I'm back up to my 160 WPM crap, and my keyboard doesn't like it. I need a really good mechanical..maybe at the end of the month Iwill treat myself!
