HotHardware posted a preview on the Intel Skulltrail Platform Motherboard

What we have for you here is an up close and personal look at Intel's Skulltrail platform D5400XS Intel ATX motherboard from a couple of different angles. As you can see, the Southbridge and dual NVIDIA nForce 100 MCP chips are actively cooled by a large fan-sink cooler. Our pics of Skulltrail from IDF showed a trio of small heatsinks, so things have changed a bit. The motherboard has four PCI Express x16 slots and dual standard PCI slots. Aluminum heatsinks cover the Northbridge and some of the components around both LGA771 Xeon CPU sockets.
