Agree with Mike on this. I checked the product page and the 1070 is no longer offered, so you would go with a 2070.
I would also recommend Windows 10 Pro over Windows 10 Home. This allows you to delay the installation of new feature releases (which come out every 6 months), which have sometimes caused problems in the past.
Then as a minimum, get 16 GB of RAM. I would also add an extra drive. You would have one system drive and an additional drive for content, renders, etc.
This will make things more expensive, but you want a system that will last you a while.
