Actually - searches bring up installations of LCD Monitors and/or Arcade Monitors in new-custom built cabinets - not quite what I was looking for.
However I did manage to find a much less complicated method.
I noticed that my Robotron cabinet's monitor shelf had holes drilled into it with T-Nuts installed in them. After further research i found out that that's how the original monitor was installed, it was installed on a board and slid into position until the holes lined up and a bolt screwed -securing the monitor.
Luckily - I found that I had this sliding shelf amoung the parts I salvaged.
Using 4 large L brackets, wood screws and industrial-strength velcro I secured the monitor to this shelf and can now slide in/out the monitor at will. I did not need to de-case the monitor.
FYI - the L brackets and INDUSTRIAL strength velcro combo is quite strong - as a test I hung the monitor upside down. Holds fast. Don't use the cheap or knock-off velcro for this type of application - use the industrial strength or teflon velcro for rough & outdoor surfaces. Pricey but well worth it.
Be seeing you,
