As the manufacturer of the Aluminum case, I want to end some speculations:
1. Yes, the housing will be redesigned for maxiumum durability and easy manufacturing but still keeping the outer design. With this, all the clips will get replaced by screws.
2. Yes, we will have a very close look at the hinges - a basic redesign of this part is very likely.
3. We will use Aluminum AW7075 which is even stronger (up to 540 N/mm²) than standard steel (such as S235JR aka St37 - 350 N/mm²)
4. The antennas will get plastic windows in the housing, so the WIFI and Bluetooth performance will (hopefully) not suffer. However, some kind of directivity may occur.
5. Before delivery we will check all components to fit in perfectly.
6. The housings will get manufactured in Germany on a brand new 5-Axis CNC machining center.
