HP z2 mini g3 graphics and ethernet

Hi,

I have some questions about the HP Z2 mini g3:

1. The model with Nvidia Quadro has 4 displayports, does this mean I can have 4 x 4k displays connected and ruinning ?

2. How can I connect 6 displays to the 4 displayports and what would be the supported resolutions for the 6 displays ?

4. Can I add another ethernet port somehow ?

5. Will Barco displays work with this device ?

Thanks in advance for your time and comments.

Thanks,
