Solution idea for a monitor that is too wide for a cab

[GameBase]

I've made a few posts here, and some of you can probably tell I'm in the "monitor selection" phase of my cab project.

Here's the deal: -

I have an empty jamma cab, that used to house Flying Shark (Taito).  It had a vertically mounted monitor in it, but the cab isn't very wide (508mm inside width).  This can just about get a 20" monitor in it.

However, I'd like to put a rotating monitor in it, but unless I get a tiny monitor, whose diagonal measurement is less than the inner width of my cab, I don't think I can do it.

So I'm toying with the idea of getting a 21" polo star from hantarex, then cutting holes in the sides of my cab large enough to allow the monitor to rotate.  I'm thinking I would mount the monitor on a circular board (at front and back) and rotate on a series of wheels inside the cab.  With this "circle" overlapping the width of the cab (coming out the holes i'd cut in the sides) I guess I could then easily rotate the monitor by hand.

Anyone done this, or something similar?  Or can anyone give me advice (or tell me the idea is crap)  

Thanks in advance!

Yes, i remember a cab from the examples page that is excactly like you describe, i think it was the mean green mame but the link appears to be broken, but i'm sure this wasn't the only one.
