Hey HW it's not the waste heat from the rad but the waste heat from my GTX I never looked at it closely till recently and I have to tell you it has an impact as an example I made a very crude sheet metal box that encloses my GTX forcing it to vent out the back my current idle temps are 36,36,35,33 they were pre box 40,40, 38,36 so there are opportunity's there I think. Woodbutcher I think for the CM HAF you would mount x3 rad up top and the x2 rad on the bottom to accommodate your power supply. My problem is I want dual x3 or x4 rads. and I need space for two mcp355/restop combos. I see the advantage to Aig's new purchase you can easily add 2x MCR320 and all your pumps and stuff. $300 is too steep for me and it needs to be enclosed to protect curios little fingers. To be honest Martin's rig from liquid labs is cool two mcr320's on hinges now that creative but it hurts my stylistic sense.
Well I'm slow to adopt anything without allot of research so who knows what will be out by the time I'm ready to strike on Dec 1st
