Absolutely right.

I read the same thing - which is why I swapped it out with this:

ASUS Rampage Extreme LGA 775 Intel X48 ATX Intel Motherboard - Retail

Great choice of motherboard, it'll perform like a beast, the fusion water cooling is only a gimmick though. That water block is crap, and the water attachments to fit different tubing make it look even stupider, if it was me I'd just attach the extra air cooling attachments.
Another word on this board, when you receive it take the entire fusion cooling system and replace the thermal grease with your favorite thermal paste. They don't place enough, and they use crappy thermal paste; which is a shame because it's an expensive RoG, its like the bentley of mobo's, but they still crap out on us!

Your system looks like a beast! Especially with the Cosmos S case, it's a beastly case straight up. Best of luck.
