[G4] Noisy G4 DP

[Jim Elmore]

I had the Apple exchange program power supply and cpu fan replacement  
done. It's much quieter, though not quiet. Mine was done under  
(extended) warranty so there was no cost.  It might be expensive to  
do out of warranty. There are some internet pages for a do-it- 
yourself fix.
