I purchased this QNAP NAS box back in 2019. It's been a great piece of kit but is now surplus to my requirements.

The NAS and discs are both in great condition. The NAS has been reset to factory default.

Details: QNAP NAS 451+-2GB (upgraded to 16GB) The NAS has 4 x Seagate Barracuda 4TB 3.5" Internal HDD | Model: ST4000DM004

I have added an image of the original invoice which shows the date of purchase and the purchase amount.

The description is taken from the QNAP website.
