After reading this post I have been looking into making my own humidor cabinet as well. So are you saying that you want to line with the luan instead of spanish cedar? From the small amount of research I did it seems like it could be a possibility if you had enough cedar from old boxes and what not to give off that wonderful cedar/humidor smell. I just don't know if the luan would be able to hold the humidity as well. Tell me what you find out or decide to do and maybe we could bounce ideas off each other.

Also do you have some sketches or a plan that I could take a look at? I will throw mine up later and possibly help each other out.

Thanks,
