I just did a big upgrade to my "home lab" (got a new switch and moved it out of my bedroom), which required some maintenance in the days after the upgrade... Running a new ethernet cable, because the old one just couldn't heck doing gigabit, reconfiguring my router and AP, just general stuff like that.
Other than that and my DHCP/DNS VM sometimes forgetting to autostart after a power outage, pretty much 0 maintenance
