Wow, that UniDisk looks like it would be perfect for a 3.5" drive to be nudged inside though adding the PSU might take a bit of work. I guess because you will be dealing with a smaller drive and this a lighter power load you can take one of those 5v/12v wallwarts, gut it and mount it inside and again have the power switch and plug on the back. I kinda did the same when I installed a hard drive inside a TRS-80 Model II.
I'd actually recommend that hack first because Unidisks grow on trees compared to DuoDisks.
I did some glance measurements and you would have to mount a half height 5.25" hard drive sideways in the DuoDisk as the case is only deep enough to fit floppy drives and not hard drives. It might still work. I'll double check on this.
