The Astek LC has water in it, but it's a sealed loop and we don't really consider it watercooling per say. It's weak, prone to breakage and no one here uses it, all WC hobby folks shun Astec, Thermaltake, and Koolance kits.
I will say to just buy the parts to properly cool that setup is over $600 easy. Easy.
It would take 2-3 hours to build the order, 15+ hours to build due to case mods to hold it all and filling/bleeding/leak testing and 20% more for warrenty costs. So 20 hours at $70 an hour I figure. About what Best Buy charges for an hour of PC work.
Plus parts costs.
