360 Rad x2 fitment issues. Please advise

I'm having a hard time finding a case that can fit two 360 radiators top and front. The cases I'm looking at are:

* [ECLIPSE P400S](http://www.phanteks.com/Eclipse-P400S.html) * [AI CRYSTAL](http://www.anidees.com/ai-crystal/ai-crystal#prettyPhoto) * [DEFINE S](http://www.fractal-design.com/home/product/cases/define-series/define-s) (the watercooling standard) * [VIEW 31](http://www.thermaltake.com/Chassis/Mid_Tower_/View/C_00003011/View_31_Tempered_Glass_Edition_/design.htm)

I'd like to utilize tow [crossflow](https://www.amazon.com/XSPC-EX360-Crossflow-Radiator-Triple/dp/B06X6M8ZCS/ref=sr_1_fkmr0_3?s=electronics&ie=UTF8&qid=1491083805&sr=1-3-fkmr0&keywords=360+crossflow+radiator) 360 radiators, but I cannot tell if there would be fitment problems because of the double ended design of the radiators. Any suggestions?

I'd like to avoid behemoths like the [D900](http://www.corsair.com/en-us/obsidian-series-900d-super-tower-case)

__Edit:__ And one more thing... In the past I've always made an effort to keep the radiators below the waterline with the water fed from the top. How do people keep air out of the top mounted radiator when it's fed from the bottom? Without a top mounted tap on the radiator, it seems impossible.
