I would like to clarify something here. Your motherboard "running hot" and "producing a lot of heat" are two VERY different things. If you have a 1lb mass that's 200C, and a 20lb mass that's 20C, the larger mass actually contains more "heat" even though the smaller mass has a higher "temperature."
You're MoBo's heat will have negligible effect on your top-mounted rad. And asking people for advice, and then telling them they're wrong, or disregarding it is rather rude.
Do a top mounted rad. If you're worried, do a top 360mm rad, and a rear 120mm rad. In a case that large you should be able to find ample room internally, requiring very minimal modding (if any) to mount enough rads to cool 2 GPUs and a CPU, and a motherboard for that matter. If you're really worried about it, throw a rad box on the rear, and mount a 240mm or 360mm rad off the back of your case. I also feel the urge to say "mounting your computer to your house severely limits your ability to move it." or something else common-sense-ical along those lines.
