I will get these glass versions as sample and let you decide:
Version A looks great (even though it doesn't have the greatest temps)!
Not convinced of B both visually and functionally; for that, I'd prefer the original option C that illram also pointed out, BUT ONLY if it's reversible so you can have the cutout over the intake for blower-style cards.
A note on the stamped-in MB stand-offs: as a few other guys already mentioned, I don't think it's a good idea to remove functionality as long as the high-end cooler situation hasn't been sorted out yet. I can see why you would want to make the change but imo the added value is not on par with the options you are taking away from people who want to get the absolute most out of the case – so essentially those people who will end up in your Hall of Fame
