Preconfigured Linux Servers for Sale?

a-singularity writes "I work for several small businesses and try to promote Linux and Open Source Software use amongst them. Several of them now use Open Office and have deployed Linux servers. Recently one of them acquired an InstagateEX2 for email serving. A Linux-running closed appliance, that does quite a few things including web serving. It doesn't, however, use MySQL which is something that their website runs. They can't configure a Linux server for themselves, and I don't have the security experience. Is there a place to buy preconfigured Linux servers that will run Apache, PHP, and MySQL out of the box?"
