Some are, some aren't. When Digital Media Designer compared the Dual 
1.25 to some PCs, the reviewer mentioned that the 3 GHz Dell was 
"church-mouse" quiet, while pointing out one of the negatives of the 
new PowerMacs was their noisy fans. The Silent PC Website is one 
place for information about quiet computing. In discussing the 
various manufacturers, it says this about Dell:

Of course, Apple is known for making quiet computers since the 
beginning. That is why I am sorely disappointed with my new Dual 1 
GHz. It can drown out every other Power Mac in the house from 2 rooms 
away. There is 660 Hz hum from a poorly installed case fan, and a 
whiney 1200 Hz resonance from the dual fan power supply that is 
intolerable. This is nothing like the 100-300 Hz whoosh made by 
moving air, regardless of volume levels. I barely care when my 8500 
with 3 hard drives and auxillary fans shuts down, but the relief when 
my Dual G4 shuts down is amazing.

The noise may be expected and acceptable in a $1500 PC, but it is not 
in a $2500 "BMW" machine from a company that markets itself as a 
maker of quiet computers. The fact that Apple won't offer the 
"industry standard acoustics declarations" for these machines (not 
even to see if claims of excessive noise are within Apple's specs) is 
a telling ommission on their part.
