The
DZ60 is a 60% DIY keyboard with split space bar, static single-colour backlighting
in the front and underglow. There is a mini-USB and a Type C version. The Type C version does not have a physical reset switch.

There was supposed to be another PCB very much like the DZ60:
DO60 but it looks like it has been cancelled.
Edit: KBDFans also has a 60% with Bluetooth support but it is limited to 3u space bars and does not support split left Shift for ISO layouts. Seems to have backlight support but it is not specifically stated.
