For the recently kickstarted project called Udoo Bolt (12x12cm maker board with ryzen embedded and arduino) i created a concept design for a passively cooled casing.
So far i have some heatpipes, the heatsinks, screws and usb front panel extention. the rest is either tbd or shipping now.
Case design change! Making it so it can support a mini itx system or the bolt to remain future proof.
