Side case fan on antec 300 (wrong section?)

[jakeface1]

I have 2 120mm intake fans in the front and the top and back fans are exhaust. Should i leave the side fan empty? If not then should it be intake or exhaust? Thanks!!

i have mine blowing cooler air in

3 fans in 120mm x 3 3 fans out, 120mm x1, psu fan x1, top fan x1

so 3 in 3 out

it comes to positive or negative pressure, and that depends on whichever the user likes better
i have 1 front 120mm intake, 1 side 80 intake, 2 rear 80 exhaust, 1 top 80 exhaust

but in your case, id make that side exhaust (neg pressure)
