I recently got my hand on a cirrus7 nimbini passive cooled SFF PC and decided to put an Ryzen 7840HS board in it (instead of an INTEL NUC)
I was eying the nimbini series for quite a while now, but unfortunately they only come with Intel CPUs - good luck I still had a AOOSTAR GEM10 7840HS board which is just about the same size like the INTEL/ASUS NUCs
In order to fit the AOOSTAR GEM10 inside the nimbini, I had to do a couple of mods...
First, I machined a custom coldplate for the GEM10 board - the coldplate will also cover the VRMs and memory chips
because the AOOSTAR board has the I/O connectors "upside down" (compared to the NUC) I needed some copper block to offset the GEM10 from the original mounting position in the nimbini case - the poor INTEL cooler needed some convincing but finally I could harvest that nice piece of copper block...
fitment testing and taking some measurements to see if it all lines up...
the custom coldplate and original nimbini coldplate are soldered together with the copper "spacer" in between...
test mounting with custom 3D printed I/O shields ...
please ignore the fan, I put it in "for safety" but it's actually not being used - turns out that the case cools well enough without additional airflow, even at 45W TDP
final assembly and connection of the board - of course the NVME drive will also be cooled by the case, using 3mm thermal pads
after about 20 minutes of stress testing @45W the temperature stabilizes well below 80C
and yeah, gaming performance is also quite good for a passive cooled SFF PC of that size
hope you liked this quick build

... still, it's as gorgeous as ever. I wish Cirrus7 had AMD based Nimbini, at least based on Asrock 4x4 motherboards.
