Are you saying the laws of thermodynamics don't apply to heat generated by servers? I can understand and appreciate the thought process of bad airflow design, ie, no hot or cold rows, or things of that nature. But you can't really waste AC. We're doing a small test deployment of a dozen or so Chatsworth chimney style cabinets, with ducted returns. When the system is up and running I will comment on it more, but it seems to make a lot more sense that what we all have been doing for the last 10 years. As for the Sun S20, is it still painted black? :)
