I think most people are misunderstanding what Case Labs (Jim) means by refresh/revision. My understanding is that it means changes or modifications to existing design that entail a major part of the case - not minor items that are easily modified by the end user.
I think Case Labs is avoiding making revisions for minor modifications because this is in essence an enthusiast case - most enthusiasts want a blank slate that offers opportunities and flexibility.
CaseLabs has been selling to EU customers quite a bit, because CaseLabs is one of the very few enthusiast cases available on the market that isn't just plain crap. If EU customers are willing to shell out the cash for the cases, then you know for sure that they're designed well.
I think it's important to remember that these cases are meant to be canvases for people, not some pre-built dream machine that comes out of a box. For that, people need to go buy a newer Silverstone or Lian Li.
As well, I think asking for features from other cases such as Murdermod is a slap in the face to Jim. Murdermod is completely different than CaseLabs for a variety of reasons. While Murdermod does feature mods for function, most of it is purely aesthetic.
