I am thinking of upgrading my current GPU but having difficulty detemining what will fit in width wise, without removing the element cassis air guide or anything...
The spec (https://www.intel.com/content/dam/support/us/en/documents/intel-nuc/NUC11BT_DB_TPS.pdf) specified GPU width limit "Dual spec limit total 39mm).
Now, first all my searchs find is that slot size is 20.32mm so this does seem odd as that will make dual slot to be 40.64
Furthermore when I follow the compatibility tool and check for GPU they tested I see this one listed:
|EVGA||GeForce RTX 3080 XC3 ULTRA GAMING||
(No longer available...)
Now the spec for this that are still up on EVGA site show this as 2.2 slot which would mean this is a ~44.7mm card.
I am currently looking at GIGABYTE Eagle OC GeForce RTX 3070 that is L=282 W=115 H=41 mm and trying to figure out if it will fit.
Thank you for posting on the Intel️® communities.
Regarding your question, we don't comprehend the 2.2 measurement EVGA site shows. However, based on the Technical Product Specifications (TPS), we can confirm that the maximum width is 39mm, which indicates that the GIGABYTE Eagle OC GeForce RTX 3070 exceeds it, and we can't guarantee that the GPU will fit into your NUC11BTMi7.

We have sold the NUC11 before i can tell you this.... there are 3 slots next to the CPU, however 1 is for the air duct for the CPU fan, its about 4-6 inches long, so if the extra space is at the back of the card (away from the PCI plate) then you have 3 PCI risers worth of space at that end, remember though you have cabling down that end as well.
I hope you are doing fine.
I have not heard back from you. So we will close this thread. If you need any additional information, submit a new question, as this thread will no longer be monitored.

Was content with the answer given until I run into this:
The review there specifically done with: Gigabyte GeForce RTX 3070 Eagle OC 8GB, probobly rev1 but as far as specifications go I see no difference.
The images in this review clearly show the GPU sitting perfectly well in the NUC 11 exterem with the air duct visible behind it.
All I can say is I find the details very confusing and conflictiong even with data from the compatibility list.
and after running into this review willing to take the chance and order a unit. I will report back and will also measure the unit myself.
The cabling in the case at the PSU end isnt the greatest (but way better than Cooler Master HC100 NUC9 case effort, we sold one of those as well), you can however remove at least one GPU power cable in the NUC 11 case, from memory there is a 6 and 8 pin power, both fed directly from the PSU, the PSU uses plugged connectors for the cables, so any not required can be unplugged and removed. Also from memory i think the 6PIN has 2 connectors on it, hence why there looks to be many power cables down that end, as there are.
As GPUs get more efficient generally they only need a single 8 or 6PIN power... I seem to remember many years ago some requiring 2 6 PIn power plugs to be used.
The second image showing the GPU on the desk, does NOT Have the CPU fan duct installed, i notice though the 2.5 width is away from the CPU, there's quiet abit of room past the PCI slots so as this image confirms i think your be ok, especially as the back of the GPU is against the PC side (which has the fan duct) so thats flat, will not be any interference, the width is required towards the outside of the case (away from the CPU)
