Definitely a really cool design there. Assuming the directed airflow really works, I wouldn't be surprised to see more motherboards coming out like this. I mean, we don't need all those sensitive electronics parts exposed, where they risk being shorted-out or physically damaged.
Reading through some of the article, I caught this interesting fact that may already be widely known: "Of the 17, 10 will be based on the P67 chipset, which won't work with Sandy Bridge's integrated graphics."
So Intel creates a new processor with built-in graphics, then releases a chipset that doesn't use those graphics? I really hope they're working on their GPGPU drivers so P67 owners see some benefit from SandyBridge's GPU.
