where can I get generic 5.25 drive cage for 3 drives and a hdd cage for 3 drives? most desktop cages are not removable, either welded or rivited aside from being an odd design. I am looking for a simple open box with "ears/flanges" on at least 2 sides, top and front so the cage can be hung from the cases top or bottom and supported at the front. if I need to I can probably fabricate my own. any advice welcome.
