Datacenter In A Box
I am surprised nobody thought of this sooner. Sun Microsystems has built a complete datacenter into a standard shipping container. All you need to supply is power, water (for the cooling system) and network connectivity. Imagine being able to deliver a complete datacenter environment including servers, storage, networking and cooling to any location where you can place the container. All this for around $500,000. Very cool.
