Tai-Hao caps are my favorite. I wish they made more colors for Alps though.
Rev. 2 of the PCB will support iRocks switches, which are similar to tactile ALPS but with a Cherry compatible stem. The top row is also about 0.5mm too high so I will fix that as well.
Making a full-case plate for the Quietkey is something I want to do, but I really don't know how to. I've played around with swill's and Inkscape but am still a bit confused on how to make it all work. So for now I'll probably still focus on PCB mount + plate for the main key block.
