Just a note: For 7bit's group order, you should order on Geekhack or on Deskthority. The robot's username is the same on both boards: "7bit_r4". If you order on both boards, you get two orders. There is no way to merge the two orders, other than 7bit doing it manually.
BTW, black G80-3000 have keys made of thick POM, not PBT. They have been laser-etched, so even if you remove the white infill, there is a relief still on the surface. Maybe you could have the keys sand-blasted, though.. I have not tried that. (but I want to)
The second iteration of Das Keyboard was in fact a G80-3000 with blank black POM keys. The current iteration has ABS keys, if I am not mistaken.
