Basically what it says in the title. I did a lot of searching in Internet. I think small form factor computers are mt best bet. But I still feel they are costly for my purpose.
I am going to be running some ansible playbooks periodically on the machine. SBCs i looked at either had very high specs for this use case and thus higher price or they had other fratures i dont want like - wifi, graphics card etc.
I am preferring enterprise hardware because this would eventually be used in business where people will not settle for anything less.
Does it need to be replaceable or upgradable?
I personally used hardware from Pine64 but its not for everyone. You also could go with an Android tablet
Not really. Just has to run till at least 5years at least. Since this will be deployed at customer site, pine64 and android both are not feasible. Thanks for the suggestion though.
