Realize that the reduction in absolute pressure means that the water block will be subject to >15 psi water pressure. This may need to be taken into consideration depending on the area inside the gasket on the waterblock (15 pounds of force for each square inch). The other thing that comes to mind is the large amount of power (aside from the cpu) that is running through that motherboard. I work with a UHV system and although there is much less pressure in the system I use then what you would be using remember that virtually no heat will be collisionally transfered away from the motherboard from the air inside the chamber. It may be interesting to see how hot things get and how fast, but you might also see how fast things melt, so it is something else to think about.
