All sound great.
My order of interest is this...
1 Paints and Stickers - We can all change the card artwork in the marque and control panel but I've cover stickers and painting the MDF panels for extreme modding.
2 Plugs n Power - Solutions for a single power cable design and power buttons.
3 Neopixel Madness - adding Neopixels to your Picade to add cool lighting effects
4 B-B-Buttons!! - Simply changing the buttons, but I'll cover what will fit and sizing etc
5 Speakers & Sound - adding an external amp and changing the speakers
