Inspiron 5675, Ryzen 2 CPU

I posted some questions on some other threads here but I  wanted to take some information I've aggregated and compile into one thread.

It looks like Dell has officially announced, on this forum, that two 2700 CPU's are compatible on the DELL Inspiron 5675 as long as you were lucky enough to purchase the model with two of the three motherboards below:

Inspiron 5675 was shipped with three motherboard part numbers. See compatibility notes below:

The two boards below are compatible with, OEM Dell 2700 and 2700x Processors -  (MDT18 Ryzen 2 R7-2700X and 8N7VW Ryzen 2 R7-2700, 8C/16T, 3.20GHz, 65w)

1. 477DV Summit Ridge + Asetek liquid cooler - Compatible
2. 7PR60 Summit Ridge - Compatible 

2700 series doesn't work at all

1. XFRWW Bristol Ridge - Not Compatible

You can find your find your motherboard's model in the System Information Console.

See Below on how to:

Click the Start menu and type System information. Select the System Information icon.

Then, in the right hand panel look for:

"BaseBoard Product"

Two questions:

1. How do I buy these,

• MDT18 Ryzen 2 R7-2700X, 8C/16T, 3.70GHz, 105w
• 8N7VW Ryzen 2 R7-2700, 8C/16T, 3.20GHz, 65w

I cannot find them anywhere I have confirmed I have: BaseBoard product 07PR60 In my system information console. 

2. I am assuming that the Ryzen 2700X model :YD270XBGAFBOX and Ryzen 2700 model YD2700BBAFBOX won't work? Is this confirmed with compatible 5675 motherboards.
