Budget is not an issue actually. This is going to be deployed for customers but i want to it to be as cheap aspossible to get them maximum value for their money. Software stack is going to be minimal. Probably alpine linux or ubuntu server. Spec wise i think even an i3 level cpu is fine. Ram 8gb, hard disk 256 gb ssd should be more than enough. Dont require any fancy wireless stuff like wifi and Bluetooth.
