For multiple USB-C ports it requires a USB-HUB-PCB or two different connections for USB-C one with key-a and the other with the old 20pin. For the current USB-C I use a PCB with a female port for the I/O and a male port on the inside. The advantage is that you can connect whatever extension cable you like on the inner male port. For example you can use a USB-C female to 20pin, USB-C female to key-a or USB-C female to USB-C male an route a through a special hole under the GPU to the GPU itself or the motherboard I/O.
@Arboreal Sorry I am not a fan of this power button.
Thanks for looking, Dan. I quite understand, apparently it is YOUR design after all!
The USB-C arrangement sounds excellent, make your own arrangement to connect to the motherboard.
I forgot to say that I did like the logo on the front. I know that some don't like it, but if it's as you have suggested, it is as discreet as the NCase M1. I rarely notice mine on the silver case, but it is good to have something subtle to break up a potentially large and plain area on the front panel.
It's all coming together very nicely; bring on the prototype
