It's not just the fanless cases (Update: It's official, HDPLEX and Streacom are skipping the Skylake NUC), the motherboards themselves are prone to freezes with WHEA errors / MCE errors.
That's unfortunate and quite disappointing. We're pulling the plug on the i3 and i5 kits, and we just don't recommend them. Our money is on the i7 version now.
