Contrary to what some sibling comments suggest, I am currently using an older HPE-2530-48G-PoEP switch with the 3 builtin fans swapped for Noctua nf-a4x20-pwm (installation went very smoothly). They are actually less audible than the disks of my NAS next to it. Admittedly, I am only using about third to half the ports and the load is only moderate most of the times but this setup has been working flawlessly for over a year now.
I guess it depends on your workload and the specific hardware involved but using server hardware with quiet fans in a living room environment can certainly be achieved.
> You imply that a website that does not mention tree planting at all, plants the most trees. Interesting.
They actually don't imply that but the exact opposite, which is "the website that talks the most about tree planting, plants the least". The way you phrase it reverses that logical implication, which is not what they said.
