I bought the angle because I have my hard drive bracket away to a larger video card installed in order to install the hard drive in the 5.25 "drive bay. One should, of course, only attach the bracket to the hard drive and then installing fixed with the angle disk. Rounded bolts are not quite as easy to apply (because it always slipped out of my hand) but with a little skill is that clear.
Conclusion: Very useful for people installing more hard disks with similar problems or you just want to. The shipping was very fast I've ordered on 10/03 at 01:00 and it came this afternoon at 11:03 at specified was 12:03 to 17:03. Would highly recommend it! ;-)
