The hyper 212 should just about fit. It's 159mm high, and the antec chassis is about 200mm wide. If we assume no more than 3 centimeters are wasted with side covers and such, that'd leave 17 for motherboard and probably 16cm for the cooler.
The zalman is smaller, so it's definetly going to fit. They've never been easy to install though, but you only do that once.
