I've found that cost is not a factor - I end up cutting myself on any case I work in, be it a cheapie or expensive, name brand like Dell, or no name white box. The good news is that once built, I rarely have to go back in.
In any event, these cases are pretty good, with folded over ends and such. No many sharp edges, either. One of the better yet cost effective cases I've found in my many years of building machines.
