Same thing here. Ordered PNY Quadro RTX 4000 month ago, nothing received yet, except third "unexpected delay".
For the fun: Also have spare Radeon Pro W5100 laying around.
I think I got everything... if you have any questions, ask below

The first step is to decide what you want your setup to be, as you'll need to know how many parts to order. There is a few different options, and once you've chosen, click on the parts list for your respective setup.
1. Single Camera w/o hub server
Parts list:
Pros
Least expensive setup
Cons
Lower attainable FPS/res
2. Single Camera w/ hub server - *RECOMMENDED*
Parts list:
Pros
allows for future expandability
higher attainable FPS/res
more reliable vs. no hub
Cons
costs more (you have to buy a second Raspi)
3. Multiple Cameras w/ hub server - *RECOMMENDED*
Parts list:
Pros
higher attainable FPS/res
more reliable vs. no hub
Cons
cost (lol, 2 cameras + hub is still cheaper than a Nest cam)
4. Multiple cameras w/ a desktop computer as a hub
This is a setup that you can build, but I haven't investigated it yet, so stay tuned on this.
My recommendation is to have a hub server regardless of the number of cameras to ensure the best possible image quality, but if your budget doesn't permit, a single camera w/o a hub server can still work decently.
