I do like the look of this case, smart and classy, and a little different.
The size constraints might be an issue, but probably overcomable. My current case is not very wide either and 120mm+ fan towers are all out so I have a Noctua NH-C14 that gives up little to the big coolers. I would think it would fit in this case, definitely with just single fan under the fins.
The video card width limit might be more of an issue, if you want a high end card in it anyway.
I would expect it to cool best with both case fans set as intakes pushing as much air through as possible, with all the restrictive filters etc removed of course.
If I were in the market for a smart mATX case this would be high on my list
