Actually, I would deduct a star, because it installed CUPS (DSM-CUPS) is insufficient, and it is quite costly to install the real CUPS with IPKG. In our case we had missed namely the payroll function in DSM-CUPS while it is active by default in normal CUPS.
Since it is absolutely awesome to have this disadvantage, both in terms of hardware and software, I let the score still at 5 stars.
My recommendation: Special NAS hard drives in, and look forward to save power and barely audible operating noise!
