Looks pretty slick, that's gonna be an awesome cabinet for sure. You might wanna consider getting Cyberpunk or someone else to do the printing on such a big piece of side-art, since Kinko's is getting notorious for ripping us Mamers off for big artwork. You should also see if you could somehow get ahold of some blue coin door buttons,
www.therealbobroberts.com might stock them, that'd be kinda neat to have that, then put blue leds behind them instead of normal lights to truly give it that BLUE feel.
The only thing I don't see on there is the way you're gonna get access to the PC, if you're gonna have the keyboard just chillin behind the cabinet, or if you're gonna have it setup so the coin door can open and you can access the front of the pc, etc. Maybe stick a power button on the back would work best? Also, what kinda sound system are you thinking of putting in there. I can suggest something: buying a 3-set of Altec Lansing speakers, take the satellites outta their cases and mounting them on the top part like normal arcade speakers, then putting the subwoofer on the bottom. Having a subwoofer can really help get that umpf from the music when playing some arcade games, like Metal Slug 3 especially, every scream from the bad guy when you shoot them sounds great with a nice extra BOOM.
