I can provide a "switch plate" made of 1/8" acrylic to use panel mount switches in. If you look at the PDF in the post on ED's forum and hide some of the case parts or use the transparent view, you can see the switch plate I am using on mine. I have some small pushbuttons mounted in it and they are not tactile, but tactile push buttons could be used.
See posts 73 and 75 in this thread for more details:

Just to be clear, I am not providing any switches with this, but can send the switch plate along and at the very least, put some pilot holes in it so that it will be easy to center and drill out the hole size needed for your switches. Alternatively, you could get some perf board and mount some tactile micro push buttons on it.
