@hi There are many fanless cases if you care to build your own, look at quietpc.com for inspiration:

They are UK based, so you will get hit with taxes if you let them build it for you, but they use standard components that you can source yourself.

https://pcpartpicker.com/ is also helpful to make sure everything fit together.

@hi @dotpk Can't speak for the Nimbus, but the Incus I've been using as my home server for the past almost seven years has been amazing.
