- Novelkeys has some boards that are sold as complete builds, like this
- Ducky, Varmilo, Leopold, and Keychron are pretty popular mfgrs for prebuilt boards, and some of those come in fun colorways. Mechanicalkeyboards.com is a vendor that carries a lot of the first three; I think Keychron can be found on Amazon.
- If you want something funkier, a lot of folks in the hobby will build a board for you
