I picked them up off of eBay. They do not have NFC (I'll post some more pics tonight) and no buttons (power and volume).
I did not try taking the buttons off my original yet as I want to see if I can someone that did it before.
The cover comes off easily. Just pop the SIM card holder out and start at that point with your fingernail and just slide it around the entire length. There are a ton of very small connectors but they pop easily and you can hear each one unlatch.
I really don't see a reason they did not go forward with the covers as well as a removable battery like the OPPO Find 7. I guess they wanted to give people a reason to buy the Find 7 other than just the QHD screen.
