    Can a PIMETA go into a zipo tin

    Has anyone built a PIMETA to fit in an altoids or zipo tin? or are these amps built for hammond style cases only. also what would have to be done to get it to fit in a zipo tin. i would take it that most if not all the caps and res would have to be smd based to do it.
