zipzoomflyhigh's advice seems sound, however, what exactly are you planning on using that case for? If you're trying to cool any components newer than 5 years old or newer then you might want to think about upgrading to a case with larger fans.
The first case for my 5 year old pc had 5x 80mm fans and that wasn't enough for an old single core amd64 3500+/7800gtx combo. I upgraded to a case with 120mm's and the temps are much better. Just some food for thought.
arterius2, I do think that is a bit uncalled for... even if his question is last decade.
