Here's an interesting concept board from Asus that is going to be shown at CeBIT 2009. "Marine" could refer to a form of water cooling solution, but Asus isn't giving up the details yet. I do know that this awesome looking board gives an air of steampunk... which will certainly receive mixed reviews.
This upcoming board will feature a new back plate that utilizes "micro-porous ceramic" that will give it a sturdy structure as well as help dissipate heat.
