I really like the fact that the top is radiator ready, but looking at it from the sides and back doesn't actually leave much room for a shroud or a push/pull configuration. I would want at least 3 inches of clearance from the edge of the mobo, or 5 inches for a proper installation - good luck fitting a "monsta 420" in there!
I would say the Lian-Li PC-A77B is the most suitable case for watercooling, since it has more room at the top for "thick" push/pull radiator assemblies. It doesn't have pre-drilled fan openings, but Lian-Li does sell radiator-friendly case tops for those of us without a Dremel. And if I need hot-swap I can install a 5/3 cage that takes up no more room than the internal drive cage.
