The Zalman CNPS9500 is small enough to allow use of all 4 fans. And for the bottom fans, you will have to remove the bottom mesh piece and cut/grind out extra holes for the fan screws to fit, but yes they do fit underneath, especially with the wheels on. In fact I wouldn't recommend using fans on the bottom without the wheels as they would be just about hitting the floor. Check my other post on page 4 for pics of fans underneath on my case.
You guys are great thanks for all the information but I got one more question
On newegg the black stacker 830 evo is list as RC-830-KKN3-GP
but on zipzoomfly it is listed as RC-830-KKN2-GP
Is there a diffrence between the two?
If so what?
