Someone at OCWorkbench forum got its hands on the first Asus P35 board that is using DDR3 memory, the ASUS P5K3 Deluxe.
The board is based on Intel's new P35 chipset, and has a crazy heatpipe system to cool the chipset. OCWorkbench will be doing a preview of it soon. Here is a picture of it, and you can check out a larger one, as well as box pictures over at OCWorkbench.
