I had a look @ their solution for the 4870x2 and, to my taste, that's one sexy block...
And the price is in the same bracket as the Razor...
However, it doesn't have stand-offs, inlet-outlet are rather close (might cause problems with certain fittings, which IMHO has no excuse given that these cards are as long as it gets) and once I close the case I don't see a sausage (no windows, yes acoustic foam FTW! :P ) so is yet another no-no for me... Function > Form...
