is the board that meets most of your requirements. The only downside is that it is relatively new and so you won't see any discounts on it for a while. The main benefit to going with the latest 7 series chipsets is native SATA 3 and USB 3 support. Older chipsets require additional controllers to gain those features and those implementations may present issues with performance
or software support down the line.
For your future SATA port needs, you can take advantage of the mini pci-e slot on found on the DH77DF (and other recent Intel desktop boards) and use this mini pci-e SATA controller card
to gain two more SATA ports.
