Old style mac mini preferably. I'm thinking of getting an optibay, removing my disc drive, and putting a 1tb hdd in there, then putting a 1tb hdd in the stock location, giving me 2tb's of internal storage with striping. Has anyone done this? Are there problems/risks to consider, other than lack of airflow from the bigger drive in stock location? I know of all the external options, and I'm not interested.
