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.
Deployment is probably more important than hardware for enterprise one-off machines.
Raspberry pis are plenty reliable, though maybe you could opt for something with a case, an N100 and a more reliable SSD, for a similar price.
