There are a lot of factors in noise level. 
The amount of fans, the condition (unbalanced, dusty fans make more noise), 
the case time, internal dampening. 

The Dual 1.6GHz Athlon MP Linux box I am running has 13 fans. Including the 
two in the plexiglass side window. It sounds like a server room all by 
itself. http://www.thecenotaph.com/pics/punisher5.jpg

I plan on getting a dampening kit from www.coolerguys.com It's how I manage 
noise, it helps a little.
