I put my Picade Console together and am happy with the result.
Looking at the instructions and video for assembling the full Picade was helpful, but of course there are differences.
I have an RPi 2B with RetroPie 3.0 inside the console.
For now I am using my HdmiPi (from Kickstarter) as my display and force the sound output to the 3.5 mm jack on the Pi which is connected to the Picade Board (Leonardo) and the built-in speaker.
One difference with the full Picade is that there is only one speaker (connected to the left channel), so no stereo sound when using the console speaker.
A few comments in no particular order:
With a Pi 2B you cannot use a long WiFi USB adapter (like the official Raspberry Pi one) since it interferes with the speaker. Using a short one (like the Edimax) works fine. Note that also the USB cable connector needs room.
The USB and the audio cable connecting the Pi and the Picade board are very long. Since there is not so much room inside the console it is difficult to route them. Here the included cable ties and mounts help. Shorter cables for the console version would make life easier.
It is important to check all the screw terminals on the Picade board when you have all the cables inside. In my case 2 wires had loosened and I had to reconnect them.
Not all the bolts followed the full Picade instructions. Used the 12mm M3 bolts for both the door clasp and catch.
The longer 14mm M3 bolts were needed to mount the Picade board.
The 2 longest M4 bolts (22mm) were used to attach the top with buttons and joystick to the base box.
All in all a very nice kit, but specific console instructions would be helpful.
