The case looks rather stunning with all the holes drilled and the protective plastic removed.
The fact that you can see all of the screws joining the pieces together was a deliberate design choice on my part. I think it looks cool.
However, if I had to do it over again, I'd do most of the assembly with Lucite-welding glue instead. It turned out that drilling the pilot holes and putting in the machine screws is a procedure fraught with peril. I stripped many a screw and split the lucite in a lot of places. Most of these mistakes are so small you can't notice them, but it would have been a lot easier just to glue most of it.
