For anyone wondering, this is the keyboard in the image at the top of the article:
https://nuphy.com/collections/he-keyboards/products/nuphy-fi...I was intrigued by the design so I wanted to share.
Interesting, their configuration tool runs in browser and they explicitly mention linux; I don't have much experience with gaming keyboards but the only one I bought in the past had some windows-only configuration software and was a bit of a pain.
(this keyboard does not appear to be QMK-based, but for the record) any keyboard that runs QMK (an open-source firmware for keyboards) will offer the same experience. web-based configurator and full linux support.
