It's quite an accomplishment for an individual. You might find the Pine A64 interesting. I got 6 of the 512MB models for $15 each. [1]

I plan on running Kubesolo on them since 1.0 was recently released.[2]

Do note that you can't cluster those 6 A64's as kubesolo runs... solo. As in: No clustering capabilities.

If you do want a controller/node setup you're better off deploying something lightweight like k0s, k3s or sidero's talos (since the latter also works perfectly fine on clusters based on pi 4 and above)
