Why XigmaNAS?
It's nice to have an expensive off-the-shelf box but how can you be sure you bought a great solution or just a shiny box? It probably has a slick interface but underneath it isn't really what you were looking for. And with many other things, once you've bought it, good luck getting upgrades.

XigmaNAS keeps going where many commercial box solutions stop. Your customized XigmaNAS solution will likely be cheaper, more powerful, and more custom fit to your needs than many commercial NAS boxes. The XigmaNAS project also sees regular development, always with the focus on stability and simplicity. This means XigmaNAS receives regular updates, some of which include new features, bug fixes, and version upgrades of included components. These updates help keeping your NAS up-to-date with the latest standards and the best working versions.
