I've looked at the Novena Laptop case; and I like it very much; but I think I might want to put your 64 bit board in it. It appears your 64 bit board is intended for a home unit. Will there be a laptop model available? The Novena unit has a 13" form factor, which is what I prefer.

I often run orther OSs from an extreme 300/400Mbs usb stick, so I need to have usb 3.0/3.1 ports to allow this rate. I also definitely need the GPIO port. How many cores will the 64 bit board allow? This wasn't immediately clear to me. Also, do I need to do anything special to allow the board to run in parallel mode, or will this be automatic and transparent to the user?
I am security conscious, so will the HW and BIOS be infosec compliant? I don't want the HW accessable over a network without the OS running. The BIOS, should be no-blob with no back-doors; and should not allow access to the HW without OS loaded.
Also, will there be 3D drivers; and will I be able to run Win10 and Other Linux, preferably in dual-boot?
