Hello Zynthianers and @jofemodo 
I just wanted to share that I managed to complete the assembling of the Zynthian in little more than three hours, enjoying the experience in the process.
I have treaded carefully, as a sort of slow mechanical meditation, so to speak, as sensibly suggested in the online manual.
The overall feeling of the device is very professional: a huge leap forward from V4, in my opinion. The metal chassis is sturdy, reassuringly weighty and well finished; the knobs are pleasantly resistant and of high tactile quality; the rubber keyboard with mutant colour-coded buttons is a pure delight in use, both visually, functionally and under the fingers.
The packaging, all in eco-cardboard surfaces with Zynthian insignia and functional labels, is a feat of successful item design, with the internal boxes arranged in a column to fill up the volume of the external container, whose lid sports in clear QR links the references to assembly instructions and software download: well thought!
The trickiest parts of the mounting procedure have been the cut/handling of those minuscule thermal pad rectangles and the safe manipulation of the flat cables’ locking mechanisms: a true clockworksmith task!
Kudos to the provision of the two small section Allen wrenches, but I believe that a professional screwdriver with exchangeable heads, like that used by Floyd Steinberg in the V5 video, would prove to be much more convenient.
If I may advance a little suggestion, I would advise to possibly ship the “bits” envelope with the screws already divided in their four families, in order to save some precious time during the assembling operations.
And, oh, I think that it would not harm to clearly state that the flat cables with one blue side underneath are reversible, thus making irrelevant which visible side carries the printed overlay.
Now, it is time to put this new electronic music portable workshop under some significant computational strain, to see how nicely it behaves!
