[Arm-netbook] BOM of Cubietruck?

SoC Allwinner A20 $8 (I assume only a bit more expensive than last year's A10 at $7) RAM chip $4 per 4 gigabit. (512 MB) x4 = $16. (Dram exchange) Flash 8GB $2 (dram exchange) Gigabit Ethernet PHY $4 (guesstimate based on old data) Intermediate total ($30)

Do you happen to know the price of the following:

Wifi+BT chip (it seems to have antenna on chip)

How much for ports? VGA HDMI TOSLI NK RJ45 2X USB PCB (board itself) headphones audio out MicroSD slot

Assembly work $4 ?

Cables Package

This will give us a very rough gross profit margin of Cubie.
