Reply to Mac Mini or iMac or MBP

Just wanted to get some input on how good either an iMac or a Mac Mini would be for music production? And also how well would it compare to say a Macbook Pro or Air

Which would you recommend out of all of those?

Also I want to know if all of them are viable as well, for example what would be the bare minimum specifications i would need for it to run stuff like Ableton and all that nicely, would the base models do that fine for any of them?
