I'm generally not a huge fan of unnecessary subforums, but I think such a section could be a good asset to this forum. The learning curve for designing and building a case from scratch is quite steep. I've been on the journey for about 4 months now, and have come across plenty of challenges and pitfalls. I've come across plenty of posts both here and on reddit from people wanting to build their own custom cases expressing frustration, and sometimes greeted with replies from the veterans to the tune of "do your research and figure it out yourself," which makes it intimidating to ask seemingly stupid questions.
There are some great resources here, megathreads, the 3D models, etc. which are all very helpful, but as far as discussion goes, there are only two relevant sections; one is the Custom Cases section, which is filled with threads from the pros promoting their commercial products, and the other is the Build Logs section, which is mostly the opposite extreme; end users showing off what they've put in off-the-shelf cases. Neither fit the albeit small niche of amateurs attempting to go it on their own. And I think this forum is probably the most likely place that people like us come to, so it could be a good fit.
