If your only concern is noise (and not saving power), then the easiest solution is to just sound-proof your case - install some foam pads or something to dampen the noise. Check out https://www.quietpc.com/acousticmaterials to get an idea of what’s out there and what you can use, but even simple random foam that you’d get in parcels would work to start off with.

I haven’t seen this in person so I can only speculate, but I bet they’ll only provide the sources as a tarball or something instead of a git repo, which will make it a PITA for anyone do actually do anything useful with it. I mean, you could potentially still build a full distro from it, but you wouldn’t be able to feasibly maintain it without the ability to do a sync and merge from upstream. So this way, Red Hat achieves their goal of being able to kill any spinoff distro, whilst still remaining compliant with the GPL.

Darktable is awesome. People rave on about Lightroom like it’s irreplaceable, but Darktable exists and is a legit alternative.
