With all the little printing projects I have sitting on my desk it doesn't leave much room for anything else. I got tired of my headphones always being tossed around the area so This was my solution. I have a Cooler Master HAF 912 case and one of the drive bays has a section to change it to a 3.5 drive bay. I popped that out and made this insert. I have no idea if it will work on any other case though. So if you have this case in particular I guess you're in luck.
