I would love to stay with ML for the moment, but I am not all that up to speed on what OS you can and can't use on each model. So if I purchased a new mini from apple with mavericks pre-installed I could still just use a ML install disc and re-install ML? Or do I have to have some other sort of setup to make this work. I don't have a mini that already had ML on it to make a clone of, so that is why I am asking.
