There is something like 5mm of the radiator that pokes out of the bottom of the case. It slots right in between the sides of the front case foot.
Imgur did something really odd to this image, so I'm not sure if you will be able to see it:
That's a a BIX SR-1, which protrudes quite a bit more than the EKWB 420 I have in there now. I have it setup in push, with additional ventilation cuts to the bottom of the case. I have not yet gotten the system fully assembled, so I cannot comment on temperatures.
