Best medium-term setup for temps

With the last few touch ups for my first rig, which I will just improve over
time rather than replace, I'm unsure what will give the best temps.
In a 900D (to future proof size), what would be optimal? Both have all
fan locations filled, with a focus on slightly greater negative pressure.

Maximus VI Formula, 4770k, and 1 ASUS 780ti SC

A) Pure fan setup (front panel + basement for intake, and top/rear for exhaust).
B) All fans, except two slots up top with an h100i (likely as exhaust).

I will, once sufficient funds are available, set a full custom loop liquid cooling setup, with SLI 780ti's, but until such a time (likely 1-2 yrs +), what's the better option?

Addendum (editing feature not working):
I'm asking this b/c of how the h100i will screw up the overall airflow, so is it worth having one?
Also, that's the 780ti w/ACX cooling, if that helps.
Yes to OC'ing for everything.
Also, for A) a High-end CPU heatsink/ fan combo, of course.
