So, the angle fit very well. A little tip, first dranschrauben the angle of the hard drive and then installed into the housing. The internal thread is a bit short, so screw it gently and with feeling to the body, otherwise you can twist the screws slightly and damage the threads.
After installation, I can not detect any vibrations or other noise.
With a little effort and care that angles are a good and economical solution to accommodate a 3.5-inch drive in a 5.25-inch bay.
