I use an Isobox which is a box that my G5 lives in and isolates the noise a bit. But it does take up extra room. I remember there being talk a few years ago about a water cooled Mac. One of the high end Macs was rumoured to have water flowing through it to cool it down. Does this mean that there are no fans just water. Does this means it is quiet. If there is a way to cool a computer quietly I am sure it would be very popular with audio/musician types. Roman.
