I think you're right about the construction. For the price of a keyboard with a somewhat-sturdier case, you could buy another 1800 (or two!). If you actually manage to cause the keyboard to fail in some way that's related to the soft plastic case, I'll be shocked. Shocked, I tell you.
I assume you went with black switches?
With Cherry you will get blacks and you will like it. (usually, if not always)
It took me a while to get the keyboard because since the beginning of the pandemic and the other half of the population of this country figuring out that you can also order stuff online, shipping has been hell.
It's really nice, actually. I don't really agree with any of the criticisms leveled. The plastic is soft, but not too soft, it doesn't feel cheap. What I rather want to talk about is the extremely tight manufacturing tolerance of the two case shell halves. There is basically no creaking, even if you press down hard which is pretty cool. That is the kind of production quality you get with a company that mentions in the datasheet of the keyboard in what sizes the palettes with the keyboards come. It's all in one mold, there are no screws in the entire keyboard case, it's all snap fit and the keyboard and controller PCB is held in place that way too. This is probably why the softer plastic was chosen - it's more reliable in this scenario and deals with mechanical stress better, even eventually when the plastic starts warping, which all plastics do. The cantilever snap joints holding the two halves together are very generously designed and IMHO will not break off anytime soon, even if you open the case somewhat often, to clean the keyboard for example. I've seen these designs done very well and very poorly. Done well they can last 30+ years. It's all about the implementation and screws are not always better here in the reliability department, especially not with plastic. Other criticisms I can't really follow but that might be my perspective - The keyboard weights about as much as an item like this should weight and doesn't seem "too light" or "too heavy". The rubber feet hold it in place in all eight directions. The cable is a cable. It plugs into your computer. It sometimes makes sense to do cables a bit more robust depending on their usage scenario and mechanical stress involved, keyboard cables normally don't see much of that though and I've never broken one in my life. I do have to mention though that this case has a very nice molded-in stress relief that's probably there so you won't rip out the JST connector from the PCB if you stumble over the cable, and the stress relief will also survive it from the beefy looks of it. I also like how the controller IC sits on it's own mini board under the keyboard's key PCB, that's a clever use of space. All in all this keyboard is the kind of design you see when some product engineers worked on the same kinds of products for a while, it'll last you, the little things have been thought of and there are no surprises. Also made in the EU, don't see that often these days.
The cherry logo at the top right of the keyboard seems to be etched with laser, then filled in with paint, just like the keycaps. They did the same with the LED legend. Looks good but at least with the keycaps it'll rub eventually off but I wanted to get new ones anyways. In my usage scenario such keycaps last about 2-3 years until the printing starts to look iffy, YMMV of course. If you ever get this keyboard and start looking for new keycaps be aware that it's not entirely standard and not everything will fit.
So yeah this sounds like some kind of review but the shitting on this keyboard by youtubers et al. really rubbed me the wrong way. I don't get money from Cherry!
