Mine was brought in the UK, but they have external power bricks anyway so you can just swap the plug end of the cable

Take a look at icybox as well they are the same, more or less underneath

I have 2 older ones under 2 different brands but essentially the same.

Not much is needed to get them up and running, plug your disks in. On mine it had raid, so the raid level had to be set first, but plug it into the machine, format the drives and off you go

How many drives? You can normally pick up cheap 2nd hand nas boxes for next to nothing
