Looks like it's got the holes for a S775 HSF too. Good call by ASUS.
I've got to say though, after seeing what trouble a few of our guys on TPU had with the ATX Rampage II Extreme, I'm leery of this board. If they made the DFI mATX x58 UV Orange, I'd be sold on it.
I wonder if this is software/emulated X-Fi or if there's an actual X-Fi processor onboard. The chip next to the audio outputs looks like it's got the realtek crab symbol on it.
