Asus KFN4-DR Dual Socket F mobo snapped
 

THERE WAS ONE naked Socket F motherboard, aka S1207, out in the open today at the messe, and it was a beauty.
This one is a dual Socket F board called the KFN4-DRE, and the spec sheet has some goodies on it. It confirms the server based DDR2-800, and then goes on to slap an HTX connector on the board. It is followed up with an integrated IPMI 2.0 for remote consoles and ASWM 2.0.
