I tell you what. If I had just went ahead and bought a Vapochill system right off the bat. I would have ended up saving money. Instead of buying 3 or 4 heatsinks and various water pumps, waterblocks, radiators, tools, cases, etc.
With the VapoChill you get the very best in cooling all in one compact case. Yeah, the up-front price "seems" high, but I can speak from experience that it isn't that bad.
Actually I should try building my own, I have a friend specialized in the cooling system of refrigerators and stuff like that. Why shouldn't I mess with freon??? Because it's not environmental friendly??
