I have the prior Mac-Mini version and it is very nice. There is actually no noise that I can here from it's location (just below my desk on a shelf). I now have a need to get a new computer for another location. On that machine I plan to run Parallels with Windows 7 (some work programs that will run on Mac). I was thinking of getting the current Mac-Mini (upgraded) or the iMac. However, I have never really liked the all in one computers but because it is more powerful then the Mac-Mini I was considering it. I really want to know if the iMac is as quite as the Mac-Mini. While reading the forums I notice a number of complaints about noise and decided to start a comparison thread.
