Definitely good to be aware of. I'm planning a build with this in the front of a Fractal Define 7, which can hold a 360 in the front and has a removable panel on the front of the PSU shroud so clearance shouldn't be an issue. But it wouldn't fit in a top-mount setup in most cases-- the same Define 7 has clearance issues with motherboard components even in a normal "push" top-mount configuration.
As for push/pull, the temperature benefits may not be huge, but similar performance at lower fan rpm/noise can be valuable depending on your goals.
