True. Anyway, on the silent PC front, the next time I build one I’m going to put in a 230mm fan. They have great airflow and are about as quiet as an encased hard drive. The only way to get a quieter machine is with one of the new solid state drives.
One thing I’ve found that helps is to look at the noise level when buying a hard drive in the first place. My wife’s PC has a hard drive that you can clearly hear running from across the room, but I’ve never heard the hard drive on my iMac.
