This is the organization that Michael mentioned the other day - Turn Key Linux <http://www.turnkeylinux.org/all>. They have a killer variety of pre-built linux images for tons of common configurations - everything from full LAMP stacks to torrent seed boxes to domain controllers. Boot up, set passwords/settings, and you're good to go.
I also just saw that they have a free "hub <https://hub.turnkeylinux.org/>" that lets you deploy directly to Amazon now for those of us without physical hosted servers. John
