Heh. My quietest is my 486 router. The noisiest object therein is the harddrive (which I am going to replace by a less noisy one).
The only fan in that system is a PSU fan which I've set to 5V blowing inwards. Works like a charm...

My other comps are kinda noisy. I'll post UPS pics once the forum they are on already is back online.
