That's why I plan on buying 2 or 3. There's got to be an easy way to get them apart? no?
No, there doesn't have to be. Most wall warts are molded, for the same reason: nobody needs to take them apart. Almost any case you can disassemble you would hear creaking when you twist it, but this makes no noise. So it's very likely plastic-welded. But nothing a heated X-acto knife can't remedy. I also have a small milling machine that I could clamp it to and carefully slice it open with a thin saw blade.
