Types of case cooling?

[Nora]

I've been looking at the new cases and not all are (air) cooled the same. Some have an intake fan on the front and an exhaust on the back. Others use negative preasure with just a large exhaust fan on the back that suck the air in threw a vent in the front. Are both methods created equal in cooling if the same air flow is achieved?

I just use intake from front and out from the back, seems to be working good. Just one piece of advice is not to put it in a dusty area and put filter on front fan to prevent dust from getting in.
