Thanks for the feedback Linwood. Yes this unit does have a cable that hooks up to the MB for a single RS232 port and the others will have to be via USB to Serial and for that I already have this StarTech unit. For a dome I would prefer a sealed unit just in case hence not building the desktop unit to sit next to the pier. What I haven’t seen is a site where you can configure an Intel NUC to your needs. Not saying such a site doesn’t exist but when I google Intel NUC I get Intel’s site and mostly Amazon. If a site exist where you can configure these units similar to OnLogic’s that would make life a bit easier. I haven’t found that yet.

I know you said you needed serial ports, but do you need an industrial strength solution? A very nice genuine Intel NUC would be well under half that price; you would need USB to Serial adapter(s) then.
I also only see one serial port on that? You said you needed 3?
The Whiskey Lake is an 8th generation NUC. They are up to 11th now (oddly I don’t see a 9th listed). That’s not necessarily bad, just a comment. Mine was a bit older, many of the newer ones require 19v which then requires an additional power conversion (not all do).
The NUC’s themselves (https://www.intel.com/content/www/us/en/support/articles/000023017/intel-nuc.html) are rated for 50C operating temperature, the same as the OnLogic one (though I suspect most do it with a fan vs a monster heat sink).
Having a sealed unit without a fan does keep down dust, maybe moisture (but there’s a lot of connectors so it’s certainly not moisture proof). But on the face of it, it looks more like you are paying double for a super durable case and lack of a fan. If you need it, you need it.
If you don’t, you could buy two real NUC’s. On a NUC and a nice NB filter. 😊
