After MUCH consideration (and the announcement of Sandy Bridge P67 mATX boards) I have settled for a final build! What you see is black = radiators, grey = fans, blue = MB, and red = 6970s.
This inspired me
from http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=103_315&products_id=29197 but it is $700!
I want to cram in as many radiators as possible to cool those 6970s while retaining a somewhat quiet fanspeed. If a few fans get mounted on the exterior, so be it as long as they have some fan grilles. I may have to remove all drive bays but this is a trade off, I can mount two 2.5" drives on the bottom of the case and additional storage can be on my NAS or external. The most worrisome radiator mounting is on the rear as nozzle space may conflict with PSU placement. A RadBox may be the only thing I can do.
I love the mounting of the MicroRes! I plan on going full side window with a black trim on white case with some black UV light/coolant in red as a subtle addition.
What do you guys think?
