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.
Thanks for these suggestions. Will look into them. Hopefully they are still manufactured and supported by the vendors.
