So here's how I mounted my 2.25" Electric Ice (Betson) trackball for anyone else who might be curious.
First you need to dissamble and trace the top shape onto your wood. Cut out the hole with a 2.25" hole saw, then use a strait bit to route out the teardrop shape ALL EXCEPT for about 1/16" (which is about the height of the lip). Your goal: To get the lip to fit snugly in the hole and be flush mount with the top of the CP. Mine is slightly lower then I would have liked, but if I chewed out too much more MDF from that area.. I'm not sure how sturdy it would be. You are shooting for this:
Now that you have this shape cut out, and made sure everything fits snugly (remember that paint will tighten everything up some), it's time to grab your dremmel tool. I inserted a small drillbit into the end of it like so.
This is great for getting into small places which my clunky drill could not handle. What tight spaces you ask? Look:
Insert the top plate snugly into place
Plunge sideways through the plastic, into the wood. I had to modify the corner and remove some plastic to access the top right corner securely.
Three 3/4" screws along with the tight routing job and the 2.25" hole hugging the lip.. this thing ain't going anywhere! Here's what it looks like from the other side:
Now place the bottom of the trackball unit back in place, and secure the four screws which hold the bottom and top together. Since the top is secured into the wood, these four screws will keep your bottom in place. The result is a pretty decent trackball mount (in my opinion), which doesn't allow any unusual dust to enter since like some other techniques of removing the top. Plus, it doesn't force you to loose room on the surrounding sides of the trackball because you had to use brackets to hold it all in. The install of all the LEDs, cherrys, etc.. I need all the room I could. Here's the final result:
I have most of the other parts/guts installed, and will post pics of how I did that once I wrap up the wiring. Hope this helps somebody... mounting these trackballs seems like there's really no one way to do it if you are abandoning that mounting plate.

Door looks great! I need to restore a couple of mine... a question. after cleaning with the Dremel disk, how did you paint it? what paint, etc?

That's a clever way to mount that trackball. Nice finish with the paint too.

I agree, it's great to have the trackball recessed, and this is a very nice way to do it. The Galaxian CP (wood with metal on top of it) makes it possible...... :D

Looks very nice! Keep on 'hotrodding' :)
