I still have the first prototype, actually, though it's not in an entirely usable state (had to transplant the cables to the 3rd sample, which went to The_Cheese). The second sample went to w360 for evaluation (that's the one that had subpar exterior panel edges due to NCT vs. laser cutting).
It's true I should have had one of the production cases air shipped to me so I could sort out the filter business and whatever else; I just didn't anticipate that I would need to at the time those arrangements were being made. The filter thing is really my fault for waffling on; they'd have had the order page up on their site 6 weeks ago if I hadn't emailed them to hold off on it because I thought I could come up with a better design. Now it's the holidays and the person that was arranging that won't be back until a week into January. Ah well.
As for serials, since they're being distributed more or less randomly to (nearly) everyone else, I don't really feel like I should be exempt from that. I know some people were kind of bummed they didn't get a low number because they backed early or were on the list or whatever else, but I understand why w360 elected not to try to do that. Coordinating between manufacturing and packing the cases with the correct serial, color, top cover, and then making sure the shipping company gets everything right and hoping everyone gets exactly the right thing, all through phone and emails from halfway around the world... I can't blame him. He's got his hands full as is with replacements for damage/defects, or the few people that got the wrong color.
Well, considering you and Waha had never done anything like this before it didn't go too badly. It could have been much worse in fact. If you decide to try another project you at least know more on how best to go about it. For a first attempt I think you guys did pretty damn good. My hat is off to you and Wahaha.
