I have a little server room here at my work. It's more like a closet. 5' x 10'. We have 5 servers, routers, hubs and 2 monitors. We currently keep the door open to let the heat dissapate but last week a janitor closed the door by accident and when we came in the morning, the servers either froze up or shut down because of the heat. So now we're looking in to getting some kind of air coditioner for the room. I was wondering if anybody out there had any suggestions. I know nothing at all about ac units except that it's supposed to cool down the room. Any tips, models, suggestions would be appreciated.

thanks
