ServerMatrix isn't exactly what I would consider fully managed. If you're looking for what is considered Fully Managed (For an example RackSpace) then you should be prepared to pay more.

It is also best to get a server directly from the company that will be managing it instead of hiring techincans as you got the company that manages your server right at the data center unlike the technican that you hired has to contact you and then you got contact your provider. It is alot easier to just pick a managed provider directly.
