Hey me too. Well I will be if i ever get enough time to finish make an evaporator

Radiators suitable for liquid cooling a PC have been spotted in Aluminum, Brass, and various other Copper alloys
Well brass is copper with an anticorrosive element added (zinc), so thats fine. As for aluminum, I haven't seen one sold in ages. Maybe with some crappy kits though, I don't pay too much attention to the low end stuff so I could be missing some (sounds like something koolance would sell).
