Hi I am planning to buy a new workstation and I am hesitating between a mac pro and an iMac. Since money is not so much of an issue right now, I could go with the extra power and flexibility of the Mac Pro. However, I am concerned about the noise generated by the machine. I have already used an iMac at work so I know it is silent most of the time, however I have never used a Mac Pro. So, can people currently owning a Mac Pro tell me how noisy it is when "idle" (i.e. not doing anything power-consuming), and how noisy is it when working hard on encoding a huge H264 video or compiling lots of code? Thanks, Snorby.
