Ah, thanks! I feel a little silly having overlooked that link. Pretty nice, considering the minimal cooling needs and raw power. I feel like this is exactly the sort of rugged, simplified system needed for use in a plant.

We use Poweredge VRTX systems in our branch offices to run minor stuff. It's not too pricey compared to this Orange Box and it's an easy way to replace what in some cases could be almost a full cabinet of systems in to 5U space.
