Hi @all!
FYI, i’ve been testing this NVMe expander for the RPi5:
It fits perfectly the V5 case! Like designed for it!! 
Off topic
BTW, note the new position of the SD-card connector in the main board. I had to short the distance and improve the wiring so the sdcard synchronous signal could travel the distance in less than half period at the faster frequencies supported by the Pi5. FYI, RPI5 supports SDR104 cards at full speed, what means the bus frequency is 208MHz, compared with the RPI4 that only supports DDR50 with the data bus running at 48MHz. If you do some calculations, you can see how close to the physical limit we are, so every mm counts and i had to deploy “best practices” for routing high frequency signals. Much fun when it finally worked! 
This is the detail of routing:
Note the track-length matching, to keep the signal synced and the “big” separation between tracks to avoid cross-talking.
Regards!
