Most of the things on r/homelab and elsewhere are not wooden racks. Most are expensive server racks retrofitted to be vanity projects to serve videos to at most 2 people in a home. It's fine, it's just that people should be honest about what these are.
I got kids. So I got a lot of toys in the living room. The small office I got, does contain a printer, a PC, a space for my laptop plus dock, a server, a switch, and a small cluster. But what I don't have is more space. I don't have space for a rack.
Furthermore I've been replacing industrial grade fans (in switches, desktop, the cluster and the like) which make a lot of noise (and cool very well) with Noctua which are expensive and have less CFM but are silent enough.
