On a side note, these forums wouldn't really be here if people didn't somehow copy other people's ideas for arcade machines...
Well, there's taking someone's ideas and applying them to suit your needs. Then there's copying. Tomato, clamato.
I will say this though, it's nice to see you didn't ruin this build with ugly art. I like the finish you've got on the wood, and those stools are the TITS. The one thing that always sticks out like a sore thumb on these builds (except the Aussie version) is the cutouts for the control panels, a little more attention to detail in that area and these things would be super sweet.
