Read it again.
The rating of motors are different hence new ESC may be required. I believe they also simplified the design of board from easy manufacturing point of view. I hv not seen the new board so can't comment.
Clean the blood from those props else that would create unbalance> unbalance would create vibrations> vibrations would create extra stresses on shells> shells would crack> you will see more blood in forum So better clean your props now

Probably not add strength, but its good reference point to identify the shell variants.
This begs to be asked.... How would you know whether this does or doesn't add strength without any extensive testing?
The best way to mount a motor is to mount it on a flat base. That way you don't have to prove x braces to support raised mounts.
Unless I've miscounted, you've got this same question running on 3 separate threads now. But I'm only going to say this once.....
I'm sorry for posting in multiple threads, I just haven't gotten an awnsers till now thanks to you and msinger. The only thing I can see is the legs and vents as mentioned in another thread (My biggest fear... has happened! HELP!!!). The shell did not come in a DJI part box, if it did I would be sure it is genuine. The guy said the get a bunch from DJI and sent me some pictures. It came in red bubble rap like it came to them from DJI. the shell comes with some wires and the leds. Did not know DJI made them with those. Other than the legs and vents, it all looks good.Unless I've miscounted, you've got this same question running on 3 separate threads now. But I'm only going to say this once.....
Given the global nature of supply of things now, I would guess that DJI don't actually produce all their shells themselves in one massive factory but hive the work out the various and possibly numerous other factories within China, probably with a fairly cursory nod to quality control on location. Given that, I would think that it would be almost impossible to say definitively.
However, you seem to be doing the correct things - carefully inspecting the shell for obvious defects and anomalies and evaluating the general quality of what you have - the characteristics of the plastic, the good finish or lack of, and overall 'feel' of the product.
Of course, where you buy from is another indicator. You are more likely to get a knock-off from, say, a dingy back-street market in some un-named Chinese town than you are if you order from a DJI-authorised supplier. If you bought off Ebay or similar then you were able to look at the seller's feedback which can (but isn't always) a good indicator of whether people are happy with what they bought from that supplier.
Beyond that, I don't think there's much more that you can do. Even if some official hologrammed mark of authenticity were present, then that's easy enough to forge as well....
So, assuming that you've not spotted any serious failings in the quality of manufacturing or specification, I think you just have to assume it's OK, whether having been confirmed as 'DJI-produced' or not, and strap it all together and hope for the best.
I have a knock-off Chinese copy of a Honda generator - It's been going strong for years now....
