Are you positively sure you're all out of Nexus 6 Motherboards?
I need that part. Carrier and capacity doesn't matter, I just need that board. Also, Why such a price gap? $69 sounds like a good price for a 32 GB board, but some of the 64GB boards are $200. I can get another nexus 6 refurb from ebay for that.
Anyway, you're all out of stock of every variety. And while you're looking, a Rear Panel would be nice too.
Is this a good question?
