1. 0.5l of metanol
2. 0.3l of concentrated antifreeze for corrosion protection.
3. 1.5-2.0l of distilled deionized water
4. 5ml of my favorite biocide for germ protection (viridis nittens - that's in latin and I do not know if you have that in your place, but those 5ml of 1% of it in ethyl alcohol solution have my 3l color bright green

I use EHEIM 1250 pump, 1/2 tubing (think it's vynil) and a 40x60cm full copper automotive radiator (it IS expensive... ah.... grrrrrrrrrrr...)
As for now I have my P4 Northwood 2.4C@3.0GHz at 1.6V at 34C with passive cooling and no case fan or fan on the rad, system temps are on par.... yeah, it IS hot here already...
