Isolated Frontier Systems that see a lot of heat?

I'm looking for a "Frontier-Style" system that is isolated enough to be considered "Wild" and "Barbaric" for a Campaign that would be low-key space western or space pirates. A frontier system where the influence of the galactic empire is very thin, where you could see a lot of heat and action with space pirates and bandits ; a system that would be very much akin to the wild west, the klondike or even Afghanistan.
