Ours is a ~2 ton unit cooling a lot more than just the server, telephone, and network gear. There is a water heater, ice maker, and UPS's but it does a good job. Cost was about $500 and that even include part of the 3 year warranty extension. The room is about 20 by 20 feet with drop ceilings that are about 12 foot high.
