For those interest, I post a photo of the inside of the Acer V3-372.
The machine was easy to take apart. All screws holding it together were exposed (none hidden underneath the rubber feet).
Of note:
- There is a second RAM slot allowing 16GB of RAM in total (I haven't tried whether 32GB is supported). RAM is standard DDR3L
- The SSD is M.2 SATA. I was disappointed that it was not a NVMe or PCI-E
- WIFI uses M.2 slot also
- Battery is ~48Wh
When I received the machine, I noticed the RAM was not seated in the slot properly and I re-seated it to avoid problems. Also I moved the antennas crossing the SSD ribbon cable so that they run on top of the cable (from this view) and taped the ribbon cable down to the metal. I did this to increase distance between the two in case interference caused any WiFI problems.
