I'm thinking about building a storage drawer for my 3.5" drive bay as I can't find one. I've found plenty of ones for the 5.25" drive bay, but it doesn't seem that they make one smaller. Anyone ever attempt something like this, or know if it's been done? I want it to be a decent drawer, but can't find any drawer runners small enough. Don't need much space in the drawer, just want someplace to put my sd cards so I don't lose them (I have a tendency to do that )
