One of my favorite features of this case is the slide in drive bay mounts. After breaking out the metal plates simply attach the included drive rails to your 5.25” drives and they simply slide and click into place. The one unexpected snafu I ran into, and it is quite minor, is that I was not able to just take the drives out of my SX-830 and slide them into place. It was necessary to use the second set of holes in the drive rails and the issue was gone. This is because the drives sit a little bit further back in the FS-710 than they do in my SX-830. One other quick note that I have never seen mentioned in an article regarding this case is that the excess drive rails can be stored in the grooves on the floor of the case interior.
