Hello everyone!  I'm starting on my second build today.  This one will be a bartop for my 4 year old son that I hope to complete by Christmas.  I call it Project Leftovers because I plan to use mostly stuff I have leftover from my first arcade build a couple of years ago (but I will be using it as an excuse to pick up some goodies to upgrade my full size cab  

).  I'll be using the Weecade design but I might make a few modification.  Today I will be working on finalizing the Retropie setup and tomorrow I'll be doing most of the cutting.  Hopefully this project will move fast as I have a short deadline and most of the things I need.  My main worry is getting the artwork printed up in time.  Please feel free to add comments or questions to help me with my build.  I love reading all your suggestions to other posters. 
My supplies list is:
Leftovers1) 3/4" and 1/2" MDF.  I'll probably use 3/4 for the sides and 1/2 for everything else
2) Red and black Happ push buttons.  I was gonna use these on the full size cab but my wife persuaded me to upgrade to LED's.
3) Red T-molding
4) Raspberry PI 3.  I know, I know.  But before anyone starts in on me for using a Raspberry Pi, I originally bought this to use as a Plex media center but I had 
    trans-coding issues on some of my devices and I couldn't get the external hard drive to spin down so I scrapped those plans.
5) A spare 64gb micro SD.  Being 4, my son only likes to play ~10 different games out the thousands I have so I've got a list of ~75 MAME/NES/SNES/Genesis 
    games I've put in Retropie.  I still need to add the artwork and snaps as well as add a theme (probably the comic book 4:3)
6) Leftover white LED light strips for the marquee
7) Old 19" 4:3 computer monitor

 surge protector
I had to buy the USB zero delay encoders as well as the joysticks (grabbed two Happ competition's from GGG). I bought a power socket and computer cables so he can cut the bartop on without having to open it up.  I also bout some cheap USB PC speakers but I've been reading that the PI can't power them.  Anyone tried to use these?  If not I guess I need to grab a powered USB hub also.
Below is the artwork I've been working on.  He's big into superheroes...like most boys.  I've not sure how the background will look with the red T-molding and buttons thought.  Thoughts?
