I got these boxes and they are nifty designs, a great step up in every way. Burning in overnight now.
This is a really nice, extremely compact layout! One thing that confused me is that the DIMMs are split: one goes on top half, the other goes on the bottom half.
Bottom
Top
You may notice in the second pic in each series, I removed stuff as well as installing memory and SSD. I pulled out the WiFi module and antennas, as well as the SATA bottom mount, since I don’t need it. It looks like there’s another full length NVMe port on the top side as well, which is amazing!

Thanks for the tip on the timing command @pfaffman!
