I have finished mine. I just washed the individual pieces with soap and water and they are drying now. If I ever get time, I will post all of the modifications I have done to make this case work.
Basically, I drilled out all the holes in the bottom layers and added some M3 blind rivet nuts (from ebay) to have something to screw into. Then, I redrilled holes for the standoff locations since the holes were in the wrong place for me. They needed to be moved over a few mm. I went ahead and drilled the standoff holes bigger and I used blind rivet nuts there too. Basically, having the M3 screws screw directly into the acrylic was a bad idea. So everywhere that was the case, I drilled the bottom layer out bigger (5mm or 3/16" drill bit) and added a blind rivet nut.
Last, some of my keys on the left side were binding up on the top layer, so I used some 220 grit sand paper to removes some of the material so that the key caps would not bind.
I also figured out how to mount a sparkfun mini USB breakout board so that I could have detachable USB.
