Well you have a nice box with the QNAP, they are not bad the interface isn't as nice as Synology its gotten a little better with the newest beta. I think the main issue here is the box you have is an AMD version and xpenology boot loaders don't have the proper drivers for your hardware so you might be SOL on a baremetal install but you could always run it as a virtual machine and pass the maximum resources to the VM , i think you will be surprised on how decent it will run.. You could also sell it on ebay or something else, they hold there value and then you could get the synology box you want
That's where it is really strange, because xpenology boots just fine, it finds the network cards, but it does not find my hard drives for some reason.
I will give it a few more tries with older versions. Otherwise I will go with your suggestion and hope someone buys it on ebay.
