Wow I have to look into these LCDs, the CRT monitor was awesome for getting the arcade identical graphics on most classics, but I never rotated it for vertical games either, there was a supported resolution which was a good enough compromise.
My first cabinet was a 4 player cabinet designed to support Gauntlet and the 4 player beat em ups such as TMNT, but 4 people rarely played it and I find a certain elegance in a cabinet where the width of the control panel fits within the sides rather than extends out.
Here is an unfinished photo of my old cabinet, I dont have any finished photos anymore but I added a working 4 slot coin door to it.

I was solely interested in MAME/Daphne/Zinc though so didn't have the JAMMA concerns. The monitors I mentioned have a standard VGA attachment.
If I had the space though I'd love to have replicas of the actual arcade machines for a lot of machines, APB, Dragons Lair, etc.
Good luck with your project and have fun.
