I received this keyboard for free and after fixing a few things I plan to gift it to someone as his first mechanical keyboard. The layout is so weird though...but he'll get addicted and spend all of his money on other keyboards anyway.
I've checked for hidden screws under the rubber parts and the warranty sticker but I found none. I'll try to open it with a plastic tab as soon as I'm home. Thank you!
Edit: The screws ARE hidden beneath the rubber pads. I simply didn't see them.

The board is up and running again (holy shit, that layout though.

)
Thank you for making me check again.
For anyone who also wants to disassemble their TT Esports Meka, although I don't believe there are many of these keyboards out there:
1. Remove all 8 round pads on the back of the keyboard.
2. Unscrew the back.
3. On the left and right side there is one filco-ish clip. Use a plastic chip or a knife (proceed with caution in regard to your own and your keyboard's well-being!) to open these.
4. The top cover should pop right off.
5. Unscrew the 5 silver screws holing the PCB+Plate to the case.
When removing the PCB+Plate be careful not to damage any of the cables soldered to the pcb!
