ISP fiber box is some kind of a Mikrotik, feeds into my own Mikrotik firewall. From there on I have two gigabit switches, connected to e.g ethernet outlets around the house and anything else that needs Ethernet like the Ubiquiti mesh WiFi endpoints and TV's, computers. It is housed in a rack cabinet inside a cupboard, and I also have a few Raspberry Pi's, external disks, MacBook Pro 2016 model that has been turned into a Linux server since I have a newer Mac now. Also, there's a UPS with a 100Ah external battery in the same cupboard on the floor. So a pretty minimal homelab overall.
