Roon have a white paper document on the Nucleus which you can find at  https://docs.google.com/document/d/1pUj-yFsAHPgTuV1TbcESA4va1_mxv1M_VQPJV___nuQ/edit   

It says:

"By tightly integrating high-performance hardware with an optimized operating system and purpose-built software, they provide a simple way to get the richest possible Roon experience."

That would suggest that there is some degree of optimisation. Later in the document they say:

"The operating system is assembled using a proprietary build system developed at Roon Labs. Each package that makes up Roon OS was selected and configured by hand, carefully considering how it will be used and making significant effort to keep the operating system as trim as possible, both while the system is running and at update time.

This custom approach is what enables Roon OS’s compartmentalized storage model, fast and atomic update system, quick boot, extremely small size, and runtime efficiency. It also means that our engineers fully understand the components that make up Roon OS end to end, and that we are in a position to keep things up to date or fix problems in any area of the system."

As to not affecting sound quality, I guess that's probably true at one level but if, for example, you want to use Roon's DSP functions to do some tasks like processing DSD files which can require more processing power than some other DSP tasks and you have a server which doesn't have sufficient power for that sort of processing then you would probably be justified in saying that it can affect sound quality. I also just read Kal Rubinson's comment on the Nucleus in Stereophile and the Nucleus can play multichannel music as well as 2 channel music. Some servers can't do that. For some people that may count as better sound quality if they prefer the sound of multichannel music to stereo. Being able to deliver bit perfect 2 channel music at it's original resolution with no signal processing whatsoever isn't the be all and end all test of sound quality for lots of people and not all servers handle signal processing or multichannel music equally well so I'd say that you can find differences in sound quality depending on how you're going to use the server.

BTW, it's not a "finless case". It's a fanless case and it has lots of fins  :-)

But, I've looked into it enough to believe that a properly speced Intel NUC will serve just as well at a much more attractive price point. Perhaps if it wasn't going to be tucked away, I'd be more concerned about looks and keeping it fanless, but that's not a concern for me.

But I am holding out a bit until the issues with Roon RAAT to an Expert Pro over gigabit ethernet are fully resolved.

First you said that it wasn't optimised for audio. Now you say "not much optimised" and "just simply turned off unused services in the OS". What's your evidence for those claims? You've changed from your first statement because that wasn't right so why should I think you've got it right this time? I'm not saying you're wrong this time but you were wrong last time so why aren't you also wrong this time?

It's fine to make statements backed up by evidence. Without that backup it's starting to look like you're simply saying "not much optimisation" because you can no longer claim "no optimisation" but you gave no support for your claim of "no optimisation" and that was easily dismissed and you haven't provided any support for your modified claim of "not much optimisation". As I said, you may be right but I do think we have a right to know whether that's just what you think or whether you've really got information about what Roon actually did to optimise the OS. Without some sort of decent supporting evidence there's no reason to believe your modified claim is any more correct than your original claim and you've now conceded that there is at least some optimisation which is more than none. How do we know there isn't still more optimisation than "just simply turned off unused services in the OS".
