I remember reading his posts on the XtremeSystems Forums
when he was first designing that. I've been looking for that post for the past few days to see how things were going but couldn't find it again.
He was chatting with them about forming a company to sell them online and what legal items to be concerned about. Copyright was one of them. I guess he decided to have the post removed so he could protect his invention?
None-the-less ... it is a pretty nice external WC design. I've been working on my own and recently posted some design prints on this forum.
Mine would allow for a total of 2 480GTX rads, 2 MCP655 Pumps, 16 120mm fans in a push-pull arrangement, 2 EK-250 Reservoirs and a proprietary power supply within the case. A tight fit, but should look pretty good in the smoked acrylic. ( quick, somebody convice my wife that I need time to finish it really really soon ! )
