Well, I would like to get the Danger Den Aquadrive, but right now I can't afford it. I have two Micron-interlink hard drive coolers right now which are anodized aluminum. They are the only al left in my loop, and I want to replace them with something copper. And no, hard drive coolers are not a waste to me at all as they have knocked out about 7c vs just having an intake fan on them. So, here is an idea that I have modeled that I would like to get feedback on. I can make this for about $30 total getting the 1/8" side copper from onlinemetals. How do you folks think this will work?
