Good product idea, but unfortunately limited in use (thanks to the I3).
PC with passive heat dissipation -> SILENT, nothing to say about that. Even the temperature wasn't excessive for a fanless PC. For an application that doesn't require many cores, this product could be really interesting.
My use case: VM server running Proxmox, so you need quite a few cores: an i3 is not enough. It's a shame that the i3 limits the range of possibilities >>> Take a look at the i5 version instead.
Fast shipping by LDLC, and returns handled impeccably by customer service, thanks to them :)
NB: to access the bios, press F2 on power-up (it took me a while to find it...)
