The first thing to consider is taking the TFT out of its case. I lucked out with mine; it had enough of a subframe to allow me to fit it right in there. Later I'll make some sort of bezel for it, and mount the controls somehow so I can get at them fairly easily (once I tweak the picture, it'll just be for on/off, so it may be hidden under the panel).
I'm way behind on updating my website, but here's a couple of sneak previews: the front and rear of the LCD installation. Note that I slipped a piece of sheet plastic between the screen and the panel temporarily to protect it...
I will probably neaten everything up later (including clearing out the sawdust, LOL).
It still works (LOL), and it breathes easy, having no case anymore.

If that makes you nervous, just figure out a way to add cleats or something top the back of the panel, cut a hole that matches the dimensions of the screen, and mount it as snug as you can to the back of the plywood. Be sure to not cover any vents the display may have.
