Looks good.

Have you considered putting handles to the outer bezel? They are ugly, but would make
it easier to handle the monitor.
Where will the speakers go?
How does the retaining bar work in the vertical position, does it grab
the side? I'm not sure if this would work but maybe there could be two retaining bars at perpendicular edges, so that at least one of them would grab the bottom in either position. If the bars are not too long, I think they would both fit there. What do you think?
- EDIT -
Sorry, after looking the pictures again, I see that this would not work, since there's no space for a retaining bar at the sides. Please ignore the last suggestion.
