Have to agree it is a bit tight trying to fit t molding on the control panel sides so doing the t molding first would have been easier.
Kades came in so here is a little bit about what I felt about their assembly.
You can buy the minimus AVR USB 32K without the Mini Arcade board for about 14.50 or cheaper but I found that soldering my wiring directly to the AVR did not give me the flexibility that I prefer. So I purchased the Mini Arcade board as a DIY kit to mount my AVR on.
If you do not like fine soldering do not buy the DIY kit. Soldering the Mini Arcade board should be done with a temp controlled 30 W or so soldering iron. The pins for the AVR are the most delicate. The pins for the terminal strips are larger and fairly easy to solder. Purchase the assembled Mini Arcade board to mount the AVR on if you are not adept at soldering.

http://northamerica.emukade.com/Update: When checked 2 inputs, one on each Kade did not function. Resoldered the corresponding connection to the AVR and all worked just fine. Just goes to show how fine the soldering points on the AVR are. Points had solder but it had not entered the hole so reheating the pins fixed the non working inputs.
