If the fan noise is a problem the  PM G5 isn't much quieter than a MDD G4. The  
fast ones and real work horses are the Dual 2.7 and Quad. These machines use a 
LCS "Liquid Cooling System"
You need to be sure if you get one of those models that there's no sign of 
leaking. They can be overhauled but I'd want a good one to begin with The units 
that leaked were made by Delphi. There is a replacement unit made by Panasonic 
with two pumps that I've never seen leak, this is what I put in my Dual 2.7.. 
The Delphi units can be resealed to last longer than when new.
