I used a CNC machine for the sides and the front grill, and a table saw for the rest of the parts (it was just easier to cut the square parts with a table saw in the end).
I ended up bending some plexi for the marquee bezel area (on the real cabinets, that is 2 parts, but I thought it would be easier to just bend 2 pieces of plexi and sandwhich the artwork between the 2, and it was easy). To bend the plexi, I just clamped it between 2 pieces of wood (after measuring where the bend need to be), and then took a heat gun and slowly went back and forth until it was bent to what I thought it should be. I then held it in place to verify that it was good, and then did the same thing with another piece of plexi.
I also then put a piece of smoked plexi behind the bezel area (smaller than the other 2 pieces, just big enough for the bezel area only). That way it hides the monitor case nicely.
I got the side art printed at CAG (too bad they aren't printing anymore, I was impressed with their work), and the other artwork I got printed at kinkos on various types of paper and vynil.
I know the blue is not a perfect match to Donkey Kong blue. I decided to instead match it to the blue I painted the Donkey Kong lamp with (since they are both in the same room). I just took the lamp down to Sherwin Williams and got them to mix up a match in some nice durable oil paint (that was the first time I painted with oil, and I don't think I'd do it again, but maybe I'll change my mind once I see how well this paint holds up). I like how it looks, and my wife does too, so I'm happy with it.
I stuck a TV tuner box in the cabinet, and it's mainly used as a TV for now in the babys room, but I'm sure that will change as my son gets big enough to play it.
I was originally going to go with a 2 player control panel without the trackball, but I ended up changing my mind and making it the 1 player figher layout with the trackball. I can always change the layout in the future and make a new control panel if I want to I guess.
It was alot of fun to make this cabinet, and I would love to make some more of these (a mini pac-man, crystal castles, centipede, etc... would be fun, you could line the wall like a mini arcade). I don't think my wife will go for that until we get a bigger place (I already have my full size mame cab, a pinball, soda machine, and slushee machine in our kitchen/dining room, it was a real strugle to get her to allow this new cabinet for the baby's room

)
This board was invaluable as I was making this and prior projects. Thanks for all the help.
