Having spent lots of time trying to design the perfect multi-williams panel, I have now decided to go with swappable panels instead. This is a great relief as it free's me up to build lots of panels without having to try for perfection.
I will build my Defender panel first and use it on my kitchen table to finalise the dimensions of my cabinet, but I think I'm pretty close already.
Here is my kitchen set-up, and my cabinet design.
The control panel sticks out quite a long way, that's because I like the screen 30" from my face. The panel folds down to save space when not in use.
