As promised, here are the assembly photos. For illustrative purposes I printed the spacers in RED so you can more easily see where they go. The spacers you got with your case are black.
1. First you'll start with the TIPI/32K case open. Separate (if you haven't already done so), the TIPI from the 32K board. Place the spacers as shown in this photo.
2. Keep the board level (so the spacers don't fall out), connect the TIPI to the 32K board. Then place the last spacer on top of the board as shown in this next photo.
3. Now take the entire assembly, and place it into the case. When you're done, it should look like this.
4. Place the lid on top, flip it over and put in the four screws using the supplied tool. Here's a tip for doing that. When you drop the screws in the hole, and insert the key, with the key inserted in the head of the screw (you'll feel when it's in), spin the key COUNTER-CLOCKWISE with gentle pressure. You'll hear it click as it skips over the thread. When you hear the click, reverse the direction, and spin the key counter clockwise. Doing this will ensure that you never cross-thread the screw.
When you're done, it'll look like this:
Hope this helps you in your assembly for those have picked up one of my cases. And for those who didn't... Maybe you've been entertained a bit!
