Lifting the sticker was no problem at all, but inside, on the screws holdung the metal case, there is a nasty, thin red film of colour. Any scratches will be obvious. Now I've got to wait for 33 months untill I get a silent DSO...  :'(

You mean something like loctite? If so, it's easy enough to touch-up if you crack the film, and later need to return the DSO for warranty (since you'd have to put the original fan back as well).
orbiter:
Or just remove ALL the red stuff :D
XaS:
It could easily be Loctite. But it's not on the thread to secure the screw but only on the head itself. To me it looks like its only purpose is to reveal when someone has tampered with the screws. That's why I don't know if it is wise to remove, let alone possible to remove it completely. Finally I got a device with 36 months warranty and now I can't wait until its over....  ;D

Loctite (or something similar) is often applied under and over the head (as opposed to the threads). Nothing suspicious about it like that - I've seen it many many times.
XaS:
I had a closer look on this red loctite. Its not solvable in anything I have here (Ethanol, Methanol, rubbing alcohol, lighter fluid etc.). So from my point of view there is no way to get rid of it, hence not possible to open the DSO further without them clearly noticing it when looking for intrusion marks. Perhaps they reacted with this on the newer models because of the sticker removal procedure getting known.
