This doesn't seem that overkill to me other than using fiber optics, although I've done that in the past, unless you're doing exceptionally long runs copper cabling is sufficient even at 10Gbit within a home scenario. Seems like a decent setup.
Plus, I always think fiber is cool
Within my rack I use DACs to connect all the gear, which works well since it allows maximum performance over short runs with minimal effort.
Nice setup though, my comment wasn’t meant to criticize, I think having a proper network at home is a big boost to quality of life that most folks don’t realize because they’ve never experienced it.
