Add reference design with enlarged enclosure?

Please consider sharing a reference design for larger enclosures, such as your ethernet expansion card.

I don't personally have any plans to make one. I just thought it might be good for the community.

This would be awesome. That way if we need to make a larger expansion card we can use its dimensions to have it fit in the existing expansion card storage boxes.
