So are those the only ongoing cases that I could get? I am not a big fan of the 50 dollar one, it seems low profile and I don't really like the cases that sit below the bottom of the keycaps. The treble case looks like it does a bit also, but it seems like a better option although I wish it was a little bit more stylized like the hammer was.
The $50 case appears to be a replacement of the stock plastic Poker case cast out of aluminum instead of plastic. In other words, it's not low-profile like the Tex and Pure Limited Edition cases are/were. Although they haven't come out of production, so we're all just guessing based on the photos posted.
The treble case is a standard tray case and not low profile either.
::: Other Options :::
1. Hammer 60% Cases
There was a group buy for them, but they are still being sold on Taobao and ekw808's suggestion about contacting Feng is a good idea if you want one of those. They are very heavy and beautifully designed cases. I posted some photos of mine
here.
2. Tex Low-Profile Case
I know you said you didn't like low-profile, but
Tex is making some cases and it would appear that they will have some to sell outside of the group buy they are running. For example, orange wasn't a color that was offered in the group buy, but they have a picture of it on their Facebook page.
3. Classifieds
People sell things all the time and you might find an MKC, Duck Poker, PLA Poker, or some other 60% case appear from time-to-time. It's a bit random, but it is an option.
Hope that helps!
