So the new test rig has been baptized, eh? Nice.
So after reading that through, is there any valid reason for that single/multi-rail switch? The only reason I could see is the "safety buffer", but I don't see why I should have to choose between the easy single rail and the "safer" multi-rail. IMO, if they offer a single rail, it darn well better handle whatever is thrown at it. If it can't handle it, they shouldn't offer it in the first place. Am I missing something?
Oh, and Page 6: " There is also a pair of 6+4 pin PCI-E connectors..." Ye gods, are we up to 10-pin connectors already?
