These days i'm more pragmatic. I have exactly 2 wired machines, and everything else runs Wifi. The network "rack" is simply a firewall and a 16 port POE switch, everything else network related has been retired to the closet.
My NAS is gone. With electricity frequently going above €1/kWh last winter, it seemed like a bad idea to have a NAS sitting there, consuming ~35 kWh/month. Instead i spent about €20/month on cloud storage, and simply upload everything to the cloud (encrypted with Cryptomator), and i have redundant cloud storage (different provider) included in the cost which is where my backup goes.
All that's left at home is a small ARM based machine that handles making daily backups of my cloud data locally, as well as run a small Plex library on a single USB3 external drive.
Besides saving about half my previous electricity cost (as well as all the hardware cost!), i have gained SO MUCH spare time. My firewall is completely closed (save a wireguard VPN), and i no longer have to maintain anything except the normal patch routines.
