Some notes for other first timers:
1) Be extremely careful when cutting your case! I did a pretty sloppy job with the joystick hole and put a nice scratch all the way to the d-pad as the photos will show so go slow. Another tricky spot for me were the back buttons.
What I did for those was solder my buttons to the board then put some white out on the tips of the buttons, then fitted the board into place and the white out rubbed off exactly where the holes needed to be. I then made a tiny hole with a sharp set of tweezers in the center of each white spot then hand-turned the plastic hole drill tool and tested for fit often.
2) The place where you stick the ribbon has a little black clip that flips up/down for the small ribbon and in/out for the large ribbon for the screen. So what you would do is lift up the black tab on the backboard, slide the ribbon into the slot (it will go in a little ways), then press the black tab down to secure it in place. I forced it in a number of times before realizing this
Let me say that I have never used Putty before and it was very simple to SSH and type the commands.
5) The backboard has to be connected to the main board and the power switch for it to boot properly. I was trying to boot by just pressing the button on the main board with only the screen and battery connected (to test if SD card was properly formatted) and it would act like it was booting but would invariably shutdown after a few seconds.
Enough chatter here is the finished product:
