hey high voltage pc, there are some links to the motherboard you've always wanted to read about. i took some of my time and found it for you since you seem so anxious about dually-ing your system. that just came off from the first page of the google search. hope it helps you decide on what you want to get. but too bad i couldn't get any results from google when i typed in waterblock/radiator roundup. i guess that's because there aren't any sites out there that does that huh?
