and i dont know how many intake fans should i have. I also have 2 corsair AF-120 fans laying around

Three intakes on the front should be fine. For exhaust, put one on the rear and one on the top-rear.

 

You may have to play with the front fan curve to get optimal airflow.

I'm hesitant to put fans on the top side towards the front because it may draw air away from what the front-side towards the top is pulling in. Also in this setup, assuming all fans are identical, you'll create what's called a negative pressure system. All this means is that air will be drawn in from all of the openings in your case. While this might sound fine, it also means dust will likely accumulate quicker as well.

Having three fans as exhaust is pointless. Don't put two fans at the top, just one.
