Bit of a question here guys...

I just received my Maximus Formula from a certain UK online store...

Well they sent me the wrong one. I ordered the Non SE version, as I won't be water cooling. They sent me the SE version with the Fusion Block. My luck. Next day delivery was 3 days late from them too, and then it's the wrong board, even though my invoice clearly states the Non SE version.

Now, my question is, will my n/b suffer with the Fusion Block over the aircooled version? If not I'll probably just keep the board to save the hassle, but if for an aircooled rig, the normal aircooled block is better, I'll be returning this board (at their expense) and getting the correct version!

Please help me out here guys, I've spent half a week waiting for this board, booked the weekend off work to rebuild and play with my new system, and at every possible opportunity something has gone wrong!
