Best fan configuration for an arc mini r2?

I will be building today and i was wondering what the best fan configuration will be for the case. I have a corsair h100i and the three included case fans (2-120mm and 1-140mm fan) because of the h100i will not be able to use either a 120mm or 140mm fan. would it be better to have positive/ negative or neutral pressure within the case?

thanks in advance for any help.

Depends.  Usually a slight positive pressure is better.
