I have never heard anyone that can swallow the price tag of that Coolermaster 830 nvidea edition worry about the cost of case fans
but that cool;
I have been VERY impressed with the thermaltake 120mm smart case fan -II
they also make them in 80mm and 90mm
they are high rpm variable, come with a nice kit for messing with the rpm adjusting. you must be careful, many fan makers sell low rpm fans, these TT's I just bought are 2800rpm @ 120mm rather quiet too
for about $12.00 each

no way would any system need 9 of these puppies (4 tops!!)
by the way; you cant use that cross side ventilation panel if you are going to use 8800 video cards
the 8800 is 12inches long and gets in the way of that panel
I have sold 4 of the full tower cooler master stacker T- somthing for $150.00 at newegg.com
they are awesome built, full of features they left no stone unturned
BTW: while you are at it, have a look at the Thermal Take Tough Power 850 watt great choice if you have an 8800 SLI plans (the reason why I keep saying 8800 is that is the claim to fame for that case
enjoy
