I originally made my U360 top mounted on my test control panel but it turned out to look pretty ugly. I now want to do an undermount. My only concern is to have support for it underneath like bolts and a nut. But that option would mean I'd have to drill a hole all the way through. I don't want to do that. I'd preffer something that will have a strong hold and will not have screws show on the top of the CP since it will be plain and bare wood. What should I do to hold it?
