I lucked out on a 6 bay QNAP on eBay for dirt cheap. It had the i5 processor with 8gb of RAM.
$45 later and I had 16gb to upgrade the RAM.
B&H had a deal for $88 for the 2x M.2 2280 SATA expansion card and went with 4tb of SATA SSD for another $200.
I changed my share settings to move everything to the array, stopped docker and VMs and kicked off mover. Let that run overnight and when finished I just shut it all down.
Upgrading the QNAP was simple enough, just open the case and drop in the two sticks. I did find a firmware update that I applied to the QNAP via usb.
I did need to change the boot order to boot off the usb instead of the internal usb that contains the QNAP OS.
