Default What cfm fans for optimal air flow

Planning for a new rig, p183 antec case and am now going over what config I should be using for optimal air flow. Just in case, there are two 120mm fan slots at the front panel which I will use for intake, one 120mm slot at the top rear which I will use for exhaust, and another 120mm which is in the standard place for an exhaust fan - right behind the cpu cooler on the back panel of the case. I will also be putting in a Prolimatech Mega Shadow cpu cooler and would greatly appreciate some insight on.

However after reading some articles on positive and negative pressure inside the case, I am inclined to listen to what some other experts and citizens have to say on this issue.
If I could get some recommendations for the particular case fan setup for
#1 the two front intake 120mm fans
#2 the top exhaust 120mm
#3 and the rear exhaust 120mm case fan
#4 would be helpful to gain insight on what fans would be good to use on the cpu cooler stated above + if they should be in a push/pull etc etc
If you could state the cfm of the particular fans and the also their db (more silent the better but don't go overboard its not a very major issue) because this would be very helpful for me. Any other links to specific products you mention and other reasonings are very welcome and I will appreciate any input.

Thanks.

How much money you got to spend on fans?
http://www.newegg.com/Product/Produc...82E16835233035 x 6

2 front intake 2 rear top exhaust 2 push pull horizontal mega mount setup. If your gonna buy Mega Id make sure your ram is low profile.

All specs for the fans are in the link under specifications. But just in case .

Bearing Type Long-life bearing - Decent Static pressure .
Should put you in a Neutral static pressure situation inside the case by using the same CFM fan through out the case.

I would recommend these fans.
http://www.newegg.com/Product/Produc...82E16835103061
They have a higher cfm rating then the xigi's. There just as quiet, and they have far more static pressure then the xigi's. Which is much more important then overall cfm rating. I have 4 of these in my case and they actually out perform my 140mm fans by a wide margin. Reduced my system temp from 27c to 23c.
