The only thing i dont like about a mist is that it runs out.. i hate things that run out.. fairly easy to make them though..

If I had the option, I'd go water/air cool instead.. so then you get the fresh cooling water like your mist.. but without having to refill it your reservoir

Of course water is not like n2o as far as coolness (both definitions apply hehe) but its consistant and doesn't cost anything. Something I thought about though for water to air would be using alcohol instead. Its liquid and stays alot colder than water. And you don't need to refill anyway so even if it costs a bit to fill it up, its done.
