So the retain the 'we can run hot with airflow' design. That's good design, I like that.
But if you've got a container with three racks of servers, two racks of UPS and a rack of networking kit, a spot of aircon isn't going to make much difference to space and weight. Shit, don't use a container, just use a refridgerated lorry.
How do I spell refridgerated?
