Sounds fun. What kind of mini PC are looking at? I am a big fan of used Dell wyse 5070 devices you find from $70, native Linux support, rather big community (easy to Google). Running one as a server and one as an mobile PC even.

One thing I would consider earlier is virtual machine hosting. Making it easy to setup, test, build and destroy a system without consequences. Virtual machines (and docker container, and more) are easy to setup and manage trough 'cockpit' and you can learn the command lines later when you need it.

Imo there is no point going directly into Industrie tools (kubernetes, docker, anisble) it may is better to first learn why they even exist by building systems the traditional way.

This is the one I am looking into.

Availability in Nepal is a tough call. I can import from India given they're available in amazon.in and aren't too big weight. But that's about it. Yeah, I am going to do VMs hosting. Everything on bare metal, easy to make and break.
