    Is it "ok" to use the Aluminum case of an old MH ballast as heat sink? I have a couple old ballasts that would be donors for a DIY thing.

    sure, i don't see why not.
    I'm no expert, but i cant see any reason why it wouldn't work. Something is better than nothing.

    Yes, if the case is thick enough.

    Aren't most of those ballast casing heatsinks to help with cooling the ballast?

    The only "non-ok" aspect that might come into play is if you have dissimilar metals touchinging, i.e. aluminum of the heat sink and whatever metal the LED base is made of (if not aluminium) you could get galvanic corrosion given the environment. But still should be fine, IIRC most every heatsink out there for LEDs both commercial and DIY is aluminum.
