I am also in the market for a docsis 3.1 modem. What are you going for?

Well, I'm running a SB6190 right now. I guess I'm going to go with either an SB8200 or a motorolla MB8600.

One thing I like about the SB8200 is that if I ever go back to running a "business" connection at home I can have a second IP assigned to the second WAN port it has.

I also plan on modifying the modem to fit into my network rack without a shelf like so: https://www.reddit.com/r/homelab/comments/ft579e/finally_got...

So the actual internal matter a little bit to me as well.

Be aware the SB8200 runs a Puma chipset. For all I know modern versions of this chipset on modems are OK now, but I have a headache that will probably never going away trying to work around latency and DOS issues with one of these in a situation where I couldn't change out the DOCSIS modem for reasons that were out of my control.

It's in my "never touch again for any reason" bucket now as a result.

Incorrect, the SB8200 has a Broadcom BCM3390: http://en.techinfodepot.shoutwiki.com/wiki/Arris_SB8200
