As of this post, I did not have the resources available to the server to allow world anchors because of limited CPU and RAM, but I just got a new "game" server which will host just Minecraft for now, which will have 2 4 core CPU's and 16 GB of RAM.

So probably just the nuke. Maybe not a "build" server, but build/survival is what I was meaning. If you have a way to World Anchor and generate loads and loads of items via Energy Collectors and Condensers its a bit...blah.
