A friend of mine got an Atomiswave cab (looks like this one)

He wants the monitor in the cab rotated to be a vertical screen.

...how hard would this be to make it vertical and (knowing OCD) make it look as clean as fuck? Anyone attempted this? Is it even worth doing it?

I'm not too familiar with arcade monitors/cabs in general and I'm kinda lamenting doing such a project if it's not even worth doing...but shit, I love a learning opportunity.
