I cut our a mini donkey kong arcade on my CNC machine (to test the jakobud dimensions before I cut the bigger one). It turned out so well, I ended up finishing it out into a lamp. There are some pics and details at
http://forum.arcadecontrols.com/index.php?topic=55628.0I have thought about making more from the jakobud plans, as it was a lot of fun to cut and put together. I recently made another nintendo shaped one (same size as the lamp but with Mario Bros. artwork) to enter a valentines box contest (had to be video game themed and the prize was a nintendo ds lite). I was able to cut it out really quick, and my wife actually ended up gluing it together and painting it the next day by herself (I cut grooves in the last one to make it easier to assmble). She had a lot of fun putting it together (I'll attach a pic she made of the assembly process to this post).
Because we were on a strict deadline with the project (we learned 2 days before it was due of the contest), she opted to just spray paint the whole thing black (I know, it's not 100% accurate to the real cabinets), but I still think it turned out pretty nice. I'll have to get a pic of the final box all put together, and post it so you can see the finished project, but I don't have any right now.
I was thinking of making a namco cabinet next (as that can be multiple games like the nintendo one as they used it for pac-man, ms. pac-man, galaga, galaxian, etc...). Once the cabinet is programmed in, it's pretty easy to scale it up and down to any size (depending on what material you're cutting it out of). I have been using 1/4" birch, but I have thought about switching to 1/4" MDF as it would be easier to assemble (there is always a slight warp to the birch which make it a little hard to put together as you have to clamp it in place while it dries).
