My apologies, I didn’t read your title properly. The Cirrus website does say it should be mounted vertically for best cooling but as @Suedkiez says he runs his horizontally. My system is in a standard Intel case.
The unit I have is a NUC10i7FNH. You would be better checking this out directly with Cirrus or Roon Staff prior to purchase.
I can’t use a measuring tape properly and when the unit arrived I realized I don’t have enough space to put it up vertically But as I underutilize it, I figured I should be OK, and so far have been. If really taxed, it would probably be good to use the approved orientation.
I agree, best checked with Cirrus, also regarding the model. They are aware of Rock.

@support - Will Intel® NUC Comet Lake i7-10710U work with ROCK?
The processor in the supported device (10i7FN*) is a i7-10710U. That in itself doesn’t guarantee it will work though. More important is can UEFI boot be turned off and is anyone else running this setup with ROCK. If the answer to both is yes then you should be OK.
This is the BIOS information on my NUC & the Intel Audio Devices in Roon. I can’t confirm that any of the HDA Intel PCH HDMI devices work only that they are listed as Audio Devices. You should definitely confirm this with the supplier! There isn’t a HDMI Surround as shown in your image.
