Well, no point hanging around. I decided "If in doubt, get on with it and worry about it later if it turns out crap!".
So I've hacked into the panel above the monitor.
I have also destroyed the front screen surround piece of the monitor itself so it is now 100% officially a project item only, as it's never going back how it was.
The result of this currently is like this:

Needs to be lowered slightly so that the underside panel behind the marquee fits cleanly over it, unless I cut a bit from the back edge of that. I think even then I'd still have to lower it a tiny bit.
Should look ok once the bezel is painted and smoothed in place etc. I figured that I needed to use the front bezel really to make the screen look alright as it needs some sort of neat edge to it, and my mill is not accurate enough (and/or I'm not!) for cutting a precise aluminium bezel out for it. Shame as I have all the gear at home for anodising stuff too, so there's good bling potential.
