Heh, thanks! Glad you like Mimic. (It would indeed take a whole lot for me to part with it.)
There's a side view cutaway drawing in the Mimic build thread showing how it fits together. My plans wouldn't do you much good, because the exact size of everything ends up depending on the size of the television you put in it - but the basic idea can always be used, with or without the marquee monitor above. You could put a traditional marquee over it. Or, you could bury the bottom and expose the top part of the main screen for the marquee, like one of Markc74's unused Blip designs, or Sealcouch's Nintendo Bartop

All that said... build what you dig. There's a wide variety of opinions here. A lot of people seem to think the super-wide Jarrett 4p aircraft carrier look as exemplified by Chance's "Flynn's" is the sexiest thing that has ever been. I totally don't get it. Chito's got a love for redemption machines, and his Monolith is pretty much taking that first picture you posted here and doubling down two or three times on it. I don't get that either, but hey, I don't have to. There's folks here that don't like Mimic. We've got all kinds. The cool thing about building your own arcade cabinet is that it can be exactly what you want.
