Build and Shoot

Does anybody know where/how/can I buy a AoS Server?
I am interested because hosting a server takes a toll on your computer..
I am aware of JestServers, Any other?

Most people use a VPS, virtual private server, to host their servers. Think of it as a server where you can put pretty much anything on it. I have seen hosts that will give a VPS for a year for only $20 so just look around.
