It's well worth the read to be honest and links all easy to find. Good fortune with your IH. I can recommend Pipe's gear. I have used 4 barebones which worked out of the box and just needed an enclosure. All 4 now been getting regular use for 3 months and all operating perfectly. But honestly...
You might consider fitting small magnets, one on underside of lid and one in dugout body so that when closed the magnets meet. This will prevent the lid from unwanted openings.
Not 3 for myself, one for son and one for a good friend. Custom wood box unless you have the tools and know how you would struggle to gt an outcome you'd be happy with. Honestly first I'd recommend is DM @phattpiggie I know he may be busy so if he cannot help you just now come back to me...
Just DM @Pipes or @phattpiggie best route, I've made 3 barebones kits into custom containers and can totally recommend @Pipes hardware which I know @phattpiggie uses. I am an IH convert and you seriously have to try it if you like the Vapcap, best regards mate
