I think DFI is going to be surprised at how many of these boards they will sell. Many say they are too late, but I dont think so. The "R" chip comes with more expensive boards, so this is really a bargain at $139, and when it comes down to $125 it will be a hot deal.
Its a full size ATX board - not like the "modified" ATX DS3.- 9.6" vs 8.4".
Plus the IDE molex is not in the wrong place.
And there wont be any install hassles since the JM 368 chip is IDE only - all drivers will be full RAID SATA Intel on all six ports, and the JM will run on legacy MS IDE if you cant figure out how to load the JM ones.
If it overclocks as good as DS3, or even nearly as good, its a no brainer.
