I was able to fix my key plip with this case. It is a sacred game of patience: the system has changed slightly since my model (C4 coupe 2005) at the detent system. So I had to break the pin of my blade to reuse the coach of this case after all removed (no bowl, or not provide). This is a normal operation, judging by the videos we can find. The fact that the mechanism is not the same stack was a little headache, I spent the time, did not immediately understood the role of the inner ring. Tip: If possible, fry the pin without any disassembly of the stop notch mechanism, it fast :)
I've had no adaptation Craft bring electronics, and the blade is the same size. This box is strictly to the original dimensions.
In short, by preparing a minimum its intervention (videos, forums) this case will not cause you any problems. And I chose this one because there is the logo (put either themselves), which is rarely the case!
