Looks like they have potential. Please report back when you get them. Interested to know if the internal volume is as large as it looks or if there are ribs and such inside taking up space.
Those dewalt cases look similar to some husky branded cases i have seen. The husky cases are made in Israel and appear to be made by a company called keter. Try looking at there web sight (keter.com) and see if they make a size that would work.

[Nice find. I could not find the foam on their site. Were you able?
