ECS is displaying the Black Series X79R-A at their Computex booth. They did not show specifications but all the features of the X79 chipset are quite obvious.
We spotted ECS' X79R-A at their Computex booth. All 10 of the SATA 6Gbps ports provided by X79 can be seen along the bottom edge.
LGA2011 is a really big socket and might be using screw retention mounting instead of push-pin. There are two levers and one must be opened/closed before the other, as shown by the markings.
The 4 quad-channel DIMM slots are arranged on both sides of the socket.
