I don’t have a home lab, but I do have my ONT, a router, an AP, an 8-port switch connecting a bunch of devices (Phillips hue hub, Lutron hub, Apple TV, PS4, and Nintendo Switch) and it’s all just a jumbled birds nest of Ethernet cables - congratulations on having such a clean and organized set up!
My UPS, home network, home server, and some Raspberry Pis are all packed onto an Ikea Kallax, and if you look in the jumbled nest of Ethernet cables you may even see them.
I've looked into 10" racks before but came to the same conclusion - I'd either have to pay a bunch to get them in Canada, or put the work into tracking them down.
On the flip side, I did steal some K'nex from the kids so modem and router could stack with room to breathe, and I think that's pretty awesome.
