Fan shrouds are supposed to ensure there is no dead zone directly under the fan and thusly improve performance. If you are placing fans to pull air from behind through the radiator do you still benefit from a Fan shroud? I wouldn't think so, but wanted to get a second opinion.
Also if you have a BIPRO2 on the front intake pulling air in through the radiator, and anotherr regular BIPRO on the 120 exhaust mount, would you push air through it to expel air or pull air in through it as well, and leave the PSU to exhuast the air out? I don't know if there will be any other fans in the case besides 3 120s, so lets assume there aren't any.
