Zorg Empire

If I were to colonize a planet for the sole purpose of building lots of storage tanks and defenses, Would it be best to build close to the sun or far away? Or would it even matter?
p.s. I now how the sun affects energy and deuterium but is there something else I should know about?

The something else you should know is that if you try this one day you will log on to find your shell has been cracked open and most of your resources taken.
