Hi NomadSoul2501, normally the Synology comes without disks and you have to buy them additionally (there is a huge selection at Digitec); and it is really not complicated to install these disks.
Included in the box: the case, 2 short ethernet cables in black, power cable in black, screws (for the memory disks, if necessary), key to lock the disks in the case, short instructions on how to put the disks in.
