Recommendations for generic amd64 router hardware?

Hi all,

can anyone recommend off the shelf amd64 hardware for balena? Maybe something NUC like.

No special hardware requirements. In fact a raspberry 3 would have enough power for my tasks - if secure boot / LUKS was supported on ARM with balena.

The one hardware I tried lost its LUKS certificate when I changed the CMOS battery, so that should preferably not happen.

Anything you can recommend? Or do you think any reasonable PC style hardware should work?
