Been thinking of doing this for over a year and finally got round to it. Found parts. Spent hours soldering, lubricating, stuffing with foam and programming QMK. So happy with the final result. It's a joy to use.
Gateron yellow switches. YMDK PCB, backplate and case. Ali Express keycaps.
It's a budget build and none of this is high end......but it has still worked out really well.
What's your QMK config like ?
The layout looks like a standard qwerty, so I'm guessing you have layers for the numpad or function keys ?
