Well, the basic physics also allows you to flip the board by 180° like this:

I also replaced the original thermal sheet, by a 1.5mm copper sheett + thermal grease.
40min to reach 80° at full load. Never smelled burned.

The reason is simple, the Amlogic S922 doesn't support PCIe:
About the N2, the SoC seems to be very interesting, the lack of PCIe is indeed disturbing, but except for storage, there is no really need for it, USB 3 can do the job.
Personally I never liked the board design of the N- series. The boards are too big, they are huge, they are as big as an Intel NUC.
Do you think that FriendlyArm may release a board using the same SoC in the near future? Because I like the compact format of their M4 and Neo's.
