Thanks for the case pointer, although I didn't see any real good interior shots, it gives me a better idea of what you're talking about.
think I'll try to fit the radiator in the lower front of the case. Two 80mm fans are mounted there right now, but with a little modifying I think I can squeeze a rad + 120mm Papst in there. I will have to modify the case big time, but I think it'll work.
Well, I'd hate to see you mess up that pretty exterior, but if you can get the airflow without restriction, it might work. How much space do you have between the inside front sheet metal and the leading edge of the mobo? IMHO a good installation would require at least 4-5" (100-125mm) plus the thickness of the rad (1" (25mm) minimum for rad / fan shroud, 1.5" (38mm) for fan and 1-2" (25-50mm) clear space for fan discharge.) more would be better as the shroud between the rad and the fan would benefit from being wider.
I'm aware of the push-pull fan concept, but don't think it's a practical approach because it's so wide if done properly - close to 8-10" (200-250mm) by the time you include air in and out space requirements. I see lots of push pull setups with the fans fastened to the rad surface, but this is a noisy and inefficient approach. I would rather see one fan with a good duct than two fastened to the rad. Per some of BillA's articles, if one uses a 38mm fan, sucking through the rad, the results are about the same.
Here's a little list of things I'm planning to buy:
Water block - Swiftech MCW462-UH
Radiator - Black ICE Pro w. Papst 120mm
Water pump - Eheim 1046
Water reservoir - AC Aquainject Plexi for Eheim 1046
Well, if you read my posts, you know that I don't like Swiftech because they mix Al and Cu in their block, and that I prefer automotive heater cores to 'computer rads' however that's not a bad setup if you plan to use and maintain your anti-corrosives. (I would get an all Cu block, or possibly a Cu / plexi one, and see if there was a better sized heater core available, but that's me...)
As to other sites, I haven't been that impressed with overclockers for the most part, but I spend about as much time over at ProCooling as I do here. IMHO, they are the experts on cooling the same way SPCR are the expert on low noise. ProCooling has a very heavy emphasis on water cooling, including block design and construction. They also think a fair bit about noise, not as much as SPCR, but they do seem to grasp the idea that computers don't need to be loud to be effective. (BTW Mike, when I'm over there I mention SPCR frequently)
