I bought one of these secondhand, so I can't leave an official review here, but I'd like to give some thoughts about this board. I had been following this group buy since before it started, but I ended up not joining because at the time I was wary of boards without dedicated arrow keys (and I do still prefer boards that have them). And when the first of these showed up in people's hands in a lighter-than-expected color, I thought maybe I had dodged a bullet. But I kept coming back to look at this page, so when I saw someone on r/mechmarket selling one that had the limited metal enter key as well as a custom coiled cable, I went ahead and bought it. And I'll have to say I'm very glad I did.
As for the case color, I totally sympathize with the initial buyers. You don't want to buy something expensive and have it turn out differently from what you expected. But in person I actually think the colors work pretty well. It can be hard to photograph, since in some light the case can appear almost like a light gray without any green at all, but I think the shot above is fairly representative of how it looks.
I actually really enjoy typing on this as well. I'm using Kailh Glazed Green China Style BOX switches, which are quite clicky, and while I'm not generally a fan of clicky switches, they are a nice change and seem totally appropriate for this board. I really like the metal Enter key, but it is a bit too heavy for many switches. I swapped in a Gateron Green just for Enter and that seemed to help quite a bit.
It's true that mine has already been "fixed" by the previous owner, so I don't have the rattly stabilizers that some have complained about, and I'll have to say that I also don't really notice any ping in the case. So someone thinking of buying a new one should keep in mind that they will probably have to do a little work to get this up to its full potential. But I'm quite pleased with it. I haven't tried reprogramming the board at all because about the only thing I would want to change is the position of the Command key for use on a Mac, and that's easily done in the OS.
