Hi, I have a dell optiplex from school that I have repaired, but there are still some issues, the case is missing some features, as the school took the hard drive and mounting caddy away, so I have no where to mount my 2.5 inch HDD. I need to know if there are any other ways to mount the hard drive, because I can't have a loose HDD when I give this to my younger sister. Also, is there a place to get replacement side panels, because the school took that too. Any help is appreciated. Thanks
