Cameras for streaming? Capture devices for streaming? Most people, on average, would probably opt for a single PC setup so performance could be an issue between the options out there? Not many good in depth reviews on the webs imo.
How about something a little different like monitor mount round up. There are a lot of them out there some as cheap as $20 others $400+ and sometimes the cheap ones seem to be as good as the expensive ones sometimes not.
Just got in a few prime cable ones in the office and even with monitors below their stated capacity once you lower them past like halfway height they just fall all the way down.
Continuing on that suggestion, common desks etc. I know a few chair ones were done in the past but I don't recall any recent ones and chairs do seem to be changing. There is more to a "setup" than just the items that have electrons flowing through them. I don't recall if I. have seen a HWC desk cable organization video (10+ ways to help organize your desk cables etc).
