This switch runs hot to the touch, even with the default screamer fans. If you swap for Noctuas it's going to die a rapid death.
The ARM series Macbooks don't support external GPUs.
Quick FYI for folks looking for a learning opportunity - if anyone is looking at this as a professional learning experience, this would be far, far too confusing and has entirely too much info. If this were a complex banking system, for example, this would be broken down into 3 or 4 different diagrams, with a dedicated diagram for each of the key systems as well, and info like IP wouldn't be included. (Just had to re-do a bunch of diagrams for one of the largest banks in the world, because they had grown to be incredibly complex like this.)
For a homelab though, I love it. I especially like the very unusual color scheme because all the colors complement each other very well. OP, you have a good eye for color.
Because people get overly emotional about stupid things. Once you get a bit older and more mature, most people grow out of that. But for the ones who never do, they think their "way" is the "right way" and if you don't do it the "right way" ... "you're wrong."
At the end of the day, if what you're using meets your needs, then it's the right choice. Period. End of story.
