I like old mac-minis, as a personal choice so far (2011-2012) with Linux of course. Any similar unit that has upgradeable memory and storage would be a good choice.

I think the Umbrel node doesn't have upgradeable memory/storage. I guess it depends how many applications you wanted to throw on it. I just keep it simple.

I used to use a laptop but just don't like the form-factor as much as ras-pi or mini/nuc type things.
