Definitely! I’ve used them for years and they are super convenient. Especially in small space living. I have a small server setup in a closet that is a direct attached raid array with an m1 Mac and an Intel nuc on top.
In general I prefer the max because it can do a lot with very minimal heat generation but using a Mac mini as a server has a few downsides that you won’t run into with a nuc. Things like arm vs x86, no way to run the OS headless, cost, etc…
