Re: Looking for a special computer
a lot of gateways and dells are really quiet, you could pick up a used one for a couple hundered bucks. you won't find one that is completely fanless since you have to have a fan on the cpu and there will be 1 or 2 on the power supply as well.
edit: of course an old pentium 1 machine I have only has a heatsink on the cpu, you could pick one of those up for dirt cheap...but still will have a fan on the psu.
When all else fails...Ham Radio!
I still have the same old HP DV9700T laptop I've had for years...still kickin'
