I don't have a lot of free time to know-how to build completely from scratch, but have been wanting to try my hand at an inexpensive build. When I saw some YouTube reviews talking about the FEKER Alice 80 I had to try it out. Got VIA to customize it, got keycaps from Amazon, and spent less than $200. Not as awesome as some of your builds, but I was pretty happy with how it turned out. Mapped the left spacebar to backspace and CAPS to an FN layer, but unfortunately had to use an elongated shift key on my right spacebar because the keycap set lacked any other options of that size.
