These videos are referring to beta units. Ultimately we decided the silicone case was a better option for various reasons. When a company designs a product it goes through multiple test iterations, they change some things to improve the design. There’s no conspiracy here I mean the youtube videos show the beta 1 units with the aluminum case.
By the time we actually put the units up for presale it was made the clear the case would be silicone, sorry if you felt that was unclear but it says this in multiple places/videos. Including on the product page:
The video was made long before we allowed anyone to pre-order. Additionally it doesn’t specify which portion of the casing will be aluminum, if you’d like to get all lawyer-y haha
Here’s a video from 2 months ago showing the silicone case:
Only difference in the cases I can remember see was that beta units were black which looked really nice and much better than the blaze orange but I believe that was silicon as well. Only aluminum cases I can remember was what @Kug3lis offered for the focbox
