Glad to hear yours is working as well! That NUC Hades is really cool. I’ve been using a smaller mini-pc for live but it’s reaching its limits. May look at an NUC next. 😉
To answer your question, I’m using an iStar USA 3u rack. I would probably get a 4U if I had to do it over again because of the variety of power unit builds that are out there. It does take up a lot of space but I bought it for the sole purpose of not having to buy a PC for a long time. I can upgrade all the components as needed.
Congrats again and thanks!
Tom
