Alongside my Bulletin Board System, media server, and Apache, I would love the opportunity to see if the Microserver could stand up to the test of running all of these servers in addition to an ArcIMS viewer.
That's an interesting page you have running, and the OpenMicroServer would sure be a power-saving alternative to host it. The question remains what threatening environment you offer that demands roughed-up server hardware? It doesn't have to be a hurricane. Or a bunch of school kids. Maybe you have a nasty house cat?
