Hi all. I have a question about "tool-less" cases. The concept is interesting, but I do not like the thought of having cheap-looking plastic rails holding my 5.25" drives in place. I have always used screws and will most likely continue to do so. My question - can those drive rails be removed and can you still use screws in these "tool-less" cases (in a Centurion 5 for example)? Thanks in advance.
