In case anyone out there gets one of these Tex TKL cases and has similar concerns about the feet, this is what I observed after going back and forth a couple of times:
- It does seem like the aluminum feet have to be screwed in from the inside the case. That means that if you want to put them on or remove them after it's assembled, you have to open the whole thing up (8 screws), take the board out and put the two short screws through the holes at the bottom.
- The rubber feet have glue on them that made them incredibly difficult to take off when I wanted to replace them with the aluminum feet. The only way I could get them off was to shove the L wrench that comes with the case down the two aforementioned holes, very hard, until they popped off, and there was a fair amount of hard to remove residue afterward.
- The rubber feet are not as tall as the aluminum feet. You can use neither, and the case will lay flat against the surface. With the rubber feet on it's like the original Filco case without the plastic feet extended. With the aluminum feet it's like the original case with the feet extended.
- The big rubber feet feel *much* more stable to me than the aluminum feet, which accommodate two small rubber pads of the same variety as the four that go at the corners and keep the case flat. As I result I much prefer the typing experience they provide.
- Despite how hard it was to remove the rubber feet and the residue, I had no problems putting them back on when I decided I prefer them, but it's probably not something you'd want to do more than once or twice.
That's it. I love this case, but I really wish it came with instructions. It would have saved me a lot of tinkering.
