Two hours later:
Fishing line worked perfectly, thin (0.32 mm / 320 um), colored one end with Milwauke pen to see the penetration. Then sawed with short, quick pulls carefully through the foam tape 1-2 at a time, went pretty fast! Just to remove the remnants ... And repaint a little. Hehe.
Holds on and moves, the disassembly is not fun at all, the included double-sided adhesive tape sits like a rock and takes with it color when disassembling. Have only removed one panel so far, so will try another test. Did anyone on Reddit recommend that you "saw" with dental floss or fishing line.

Purchased at Inet's Black Friday SALE for 1400 SEK
NOTE to update firmware to latest, mine came slightly outdated (8 months). Latest firmware is awesomely much better.
+ Works fine with Android (Samsung S9 +) and Google Assistant on Google Home Mini.
- Something small with nine panels, even at this price.
- Not completely painless installation, supports e.g. not 5 GHz WiFi. Did not accept pairing pin first.
Had really wanted integration with AIDA64 or ASUS Aura, doubt anyone is crazy enough to put the systems together, but a nerd can hope.
