3x onboard USB ports would be nice as many of our Chassis require 2x of them for the front panel hookups. An extra port would be great for the addition of an internal card reader or other such device.
I believe the big difference is this that this board has a few more connectors on the board. Didn't the former board only have 2 SATA ports? It's hard to see from this picture, but there might be 3 onboard USB connectors which would be fantastic.
