I think the best option is to just build it your self using similar
components which I have looked at before. My ideal is build a system
where you can extend the storage easily by adding another box instead of
either replacing the HDD's with bigger HDD's or having multiple targets
for the data. One target whose storage can be expanded by simply adding
another box. However, that is harder in practice to work out
