Granted I didn't buy all of this at the listed prices nor from this site. Nor did I buy it all in one shot. Water cooling is expandable so you can add more and more shyt as you go.
I only used distilled water in my loop. It isn't hard to do once you get the hang of it. Very risky though if you don't take your time with it.
