h100i help. Should I set up front mounted push pull intake

[Shnippie]

Hey all, I was thinking about getting a Fractal Arc XL and was wondering if front mounting my h100i and having it set up with push/pull would be a good idea? I'd have a bottom 140mm fan as well as a back 140mm and possibly two top 140mm. The other option is to top mount the h100i as an exhaust. It never made sense to me that Corsair advised having it as a top mounted intake, as you lose the dust filters, and go against the whole "hot air rises" thing.

So in an effort to make the case a positive environment, I'd probably have the bottom fan be 140mm and all the other fans be 120mm. Is that right? Or am I missing something. Cooling is something relatively new to me.
