http://forums.procooling.com/vbb/sho...&threadid=2330 . I've been running this pump for a couple months. I have a 10 amp PWM on the pump to control the speed and noise. Which is not much louder than a 120mm case fan. You may be able to get the other pump from jabsco now.
BTW: When are you going to get time to finsh the BlackIce write up. I also have a YY-cube that I have finshed the inside but I still have to get the green cold cathiod tube's and glue up the outside. It's name is "Borg Tactical Cube 641". Here's a link to the picture I'm using to do the artwork.
