Question, why can't you mix 1 and 2? Have the back and top exhaust as in picture 2, but have three intakes with the bottom and top front in picture 2, and bottom front in picture 1. Just something I would test.
It depends on your rig.. In most cases (considering a general gaming build nowadays) a single front intake fan along with a single back exhaust fan works well.. Coming to your query, there are few structural errors (IMO) with all of your proposed setups.. All the diagrams show a back exhaust fan which is good.. However, having the front intake fans at towards the top is not understandable.. Also, in diagrams 1 and 3, you've mentioned the top fans to be intake which is unnecessary.. They need to be exhaust fans.. Diagram 3 shows a bottom exhaust fan which is unnecessary.. Diagram 2 seems the most practical except that the front intake fan should feature towards the middle or bottom portion of the front of the case..
