Alright, I see what you are doing. So, why are you getting 3 120mm fans if there are no fan ports that size on the old case? I can see you mounting one as an intake on the side, but if the rear exhaust port is 80mm, that's no place for a 120mm fan. In your first post, I think that you were discussing a second exhaust port in the top of the case in addition to the PSU exhaust port. If so, I would recommend against that. A 2nd top exhaust would have to be farther forward and would be exhausting air that had not yet passed over the hottest components. It would also be transverse to the normal front-to-back flow of air.
In response to the question, "is it normal..?" I would say that there really is no "normal" when it comes to air cooling. However, we can talk about usual. The usual intake setup is with vents on the side of the front bezel. Sometimes these are long vertical slots down the left and right side or horizontal "gill" slots, like the Alienware cases. It is less common to see a front intake fan in the center of the front bezel. Usually there are drive bays in there instead. Just looking at the case you linked to at TigerDirect, there are 4 internal 3.5" drive bays at the bottom front of the case and no obvious fan mount in there. If the case is designed to intake air through slots around the perimeter of the front bezel, I would not recommend cutting an intake port in there or mounting a fan there.
If you have the PSU fan exhausting out the top, the rear fan exhausting out the rear and a side fan (turning slowly!) for intake on the side, the natural flow of air should pull ambient air in through the front of the case to flow over the drives for plenty of cooling there. The front-to-back airflow, pulled by the rear fan, will draw air over the CPU, motherboard chipset, and adapter cards. The side port intake will allow cooler ambient air to mix with the front-to-back air current just before it flows over the hot components. The PSU, as is often the case, will be taking in hot air from inside the case and exhausting it out. That's not good for cooling the PSU components, but it's good for the air flow in the case. The Antec P180 series addresses this concern by providing a separate air chamber for the PSU.
