If it is two loops sharing the same res, doesn't that mean they share the same fluid and the system will equalize temperature wise, the same as if it was one single loop? Doesn't this fly in the face of 2 seperate loops being better than a single loop? And how is this any different than the XSPC other than the D5 vs. the MCP355? One more thing, looking at the pictures, it appears that the fill/drain port is on the face of the res, is it possible to fill it with it installed in the 5 /14" bay without tipping your system back?

I wouldn't mind having one of these, but those are my concerns, so any insight would be appreciated.
