thanks!,
so far I stopped project from few reasons:
chip shortage: I can't buy components such as fan controller (EMC2301), PMIC controller (Attiny4), USB hub (USB2514), and 3.3V buck regulator (AP3441).
project require update and some modifications, such as better EC/PMU controller with dedicated Linux application (system info/monitor), cheaper USB hub, etc.
lack of money for ordering next batch.
not enough time to continue this project (I'm full-time employee, I'm involved also in few other DIY and commercial projects).
Looks amazing!
