Build went nicely. I'm 15 and for my first electronics project, I expected that there may be some issues, and there were, but all of them were solved in the end. Just to let you know guys that if you have any doubt, a 15 year old completed it on there first time soldering. I recommend not buying a wifi dongle and instead loading the roms by usb. It saves hastle with compatability and expensive parts (I live in Australia and the exchange rate makes prices pretty high). A tutorial on usb rom transfer can be found on the retropie site.
Thanks Adafruit for an awesome kit and tutorial!
