Hit me up. Won't cost much, especially if you can produce it to measurements as an AI/PDF layout. It will be correct to less than .2mm. I'll try to find some course cabinet style super matt finish. I can also get carbon fibre effect.
It's so annoying, if everything had worked with the screen this would be finished now. Now I've got to work out a return refund to China for the main board, and that'll take a month, maybe more. Tempted to sack it off and just buy something different from a different seller and take the risk out of that side.
I maybe had 1 or 2 quirks (I believe it didn't boot the first 1 or 2 times and then was fine). Another thing you'll need (if you don't use the server, for example you have no ethernet for the Pi) is a USB stick formatted to FAT-16 I think, to copy your ROMs onto and then RetroPi just sucks them up.
It works great with a DualShock 3/SIXAXIS controller via USB.
All the emus just ran without any configuration - you might get audio stuttering and a touch of slowdown on a Pi 1 Model B or below.
The thing that took the longest was just sorting out my ROMs and deleting the ones that I know I'll never play, so my list wasn't forever long.
