So my NUC adventure is turning into a saga lol. The SSD and Memory came today. Fitted the SSD no problem, took the memory cards out the box and thought, hmm, looks a bit large. Sure enough far to big for the slots, presumably for a laptop or PC - grrrrr! Assembling this NUC has been my biggest challenge in computing so far 
Anyway I read back through the thread and read a post from @Stopeter44 which recommended CT2K4G4SFS8266 from Crucial so have ordered this. Hope to God it fits!!
The specs for the NUC will tell you what form factor and type of RAM works well with that unit (should be a So-Dimm). ( i.e. what speeds and timings it can accommodate etc etc.)
The NUC box says to use SO-DIMM, and the description of the Crucial memory is SO-DIMM, so looking good fingers crossed. It’s a bit of a learning curve, but it’s all good.

SO-DIMM is a laptop size. This is what NUC uses. SO-DIMM is about 2" long.
RAM sticks also come in the full, desktop size. Those are ~4" long.

Thanks, @Elberoth didn’t realise laptop and NUC memory were same size. Just checked the box for the wrong size memory card I bought in error, and it says “Desktop DDR4-2400 UDIMM”, so guess it’s for a PC.
Edit - I’ve also just checked the description on Amazon and it says “Compatible devices PC/server”
Like I say it’s a good learning curve for myself, and lets hope this thread is beneficial to somebody else who is as clueless as me about NUC’s and they might learn from my mistakes by reading this thread lol.

FWIW been there done that 
At least Amazon are good at returns!
They certainly are @GregD. Went on to Amazon there to return the wrong memory and for some reason they are going to refund me without me returning it. Absolutely bizarre!!
" Refunded
There’s no need to return your item. Your refund has been issued."
Very odd indeed!
Yeah, Amazon’s customer service is hard to beat (but at what cost ultimately…?).
Nonetheless, if you’d ordered through crucial you wouldn’t find a better price for your RAM.

For four years of use, the NUC7i7DNB in Nucleus+ broke down the same way twice, the M2 system disk controller failed. Since there is no longer a guarantee, I decided to finish experimenting with this seventh generation of NUС and cases without a fan. Purchased NUC11PAHi5 and launched ROCK in a standard case with a fan. Installed 16GB of RAM and 500GB of the fastest ssd from the Kingston fury series. Also installed 4TB SSD Samsung EVO for local music.

Thanks to everyone for their help with assembling my NUC. The final piece in the jigsaw (the memory)arrived yesterday and the NUC was set up and I was using Roon on it by 6pm last night. Early days but sounds great, and the performance of Roon using HQPlayer has been very impressive, with not even one drop out which I normally encountered(albeit only a couple of times per hour of listening time)when using Roon/HQP on my Mac or PC.

Can someone help me out with a TL;DR summary, now that NUC11 and 12 are supported?
Mike NUC11 is supported and I believe Danny said they had NUC12 inbound for testing so both should be an option shortly, though you might want to want to wait a little while for confirmation.
Are you looking for this (10.12.2022)
- NUC11TNHi3
- NUC11TNHi5
- NUC11TNHi7
- NUC11PAHi3
- NUC11PAHi5
- NUC11PAHi7
- NUC12WSHi3
- NUC12WSHi5
- NUC12WSHi7
Have a nice WE

So the 12s have already been tested as well.
I didn’t see mention of that.
It’s good news
So, good, better, best is: NUC10, NUC11, NUC12 - i3, i5, i7 ?
What’s the difference between all these models (price, speed, power) for Rock?
You can compare NUC Mini PCs here on Intel’s site:
and NUC Kits here:
Generally, i3 < i5 < i7, 10 < 11 < 12. On the other hand, the vast majority of people are fine with an i3 or i5 NUC10.
The NUC12 CPUs have separate performance cores and efficient cores, and to make best use of it, the OS can start processes on either, or even move them around. I haven’t read if and how RoonOS makes use of that, but I think it is a task for the Linux kernel anyway, so RoonOS would get it for free, I suppose.
Main question is which Linux kernel version RoonOS is using now, and whether the relevant code is optional in the kernel at all and, if so, already enabled in RoonOS - I have no idea about either. However, Linux 5.16 with much improved support for this was released early in 2022, so well possible that the recently released RoonOS build 254 already has it (and if not, surely Roonlabs will include it some day):

As I’ve just bought a used NUC7i5BNH to replace my NUC5i3RYH (it’s performance has become patchy as my library goes past 100,000 tracks) I was hoping someone could confirm the 7th gen NUC will utilise an NVME drive to full potential
I can’t see anything on Intel’s specs beyond M.2 and Optane!
My NUC7i7DNKE NUC running ROCK works well with a Samsung 970 EVO Plus 250 GB PCIe NVMe M.2 (2280) SSD drive.
I also have 16GB (2x8GB) RAM, while I was building it last year.
I too was replacing a earlier NUC5i3MYBE which had provide excellent service since ROCK was launched. However I had not noticed any performance drop off from Roon before the upgrade. It was just a suitable NUC came up at a good price.
Conversely I and others have failed to get the DNKE version of the NUC7i5 to work with a variety of NVMe drives. You may well by fine with the BNH though as it uses a different processor.
