Welcome aboard, Redlava.
Food for thought on the second option: Do you _really_ want anyone so stupid that they have to be told that your build is an arcade cabinet to lay a single finger on it?

Including "arcade", "-cade", or "-kade" in the title seems like an easy answer to naming your cab, but take your time and dig deeper to find the
right title/theme -- you'll be more likely to not hate an "obvious"/placeholder title in a year or two.

It would also help us give better feedback if you mentioned the style of build (full-size cab, bartop, cocktail, cabaret, low-boy, etc.), types/examples of games you like to play (fighters, shmups, puzzles, drivers, etc.), and systems you want to emulate. (arcade, consoles, etc.)
