I like the styling, but I'm not sold on the text.
My only concern is that if you have to announce in big letters on the side that it is "arcade". . .

IMHO consider giving it a more personalized title -- examples include cabs like Retro-Futuristic/Astro, Mission Control, Alpha One, Smithotron, Two Headed Beast.
There are so many projects that have "MAME" in the title or have "-cade" on the end that they start to blur together after a while.
That said, you're not building it for me.
If you're happy and it passes the spousal approval test, you are good to go.
(If Momma ain't happy, ain't nobody happy.)
