A couple thoughts.
1 - That "Arcade series" logo should be tweaked slightly so that the line angle is completely parallel to the direction of the rest of the lines going up the side art. It is like 5 degress off, and that might be noticable on a print.
2 - I think the front would feel cooler with actual Rectangle NES power buttons instead of round buttons. If you are interested, I should have some that I can get you if you pay the shipping. However, since original rectangle buttons are gray, the artwork might need to be tweaked to make it look better.
3 - What is going to be plugged into the USB ports? I would think that if it is NES controllers and stuff, it would looks a bit cooler with actual NES ports. I would consider hacking a usb hub into a nes port, or just simply mounting something like this into it:

1- I agree and I plan on doing that, but remember this is just some paint copy-paste art

The final art will be made in Inkscape when I know the exact measurements of my control panel.
2- Interesting, could you measure them for me, so I can get feel for how they might impact the artwork. Also, how easy are they to mount/wire?
3- Those would indeed look awesome. However, even though the theme is based on the NES, it will run the 8bit/16bit console emulators. That's also the reason that I have start + select + 6 action buttons on the control panel. So the usb ports are there for plugging in controllers, whether that be generic controllers, authentic nes/snes/genesis controllers modded to usb, or just some usb knockoffs, I don't know yet.
Maybe its an option to add the controller ports as graphics to the cpo. Then instead of using the bulky Neutrik usb ports, take the usb ports from a cheap usb-hub (or extension cable) and use those. They would have a very small footprint, so they would not really obscure the controller port graphics.
Lots of stuff to contemplate
