I got a DVD duplicator from Goodwill, took out the DVD drives, and made a Greaseweazle box with floppy drives I stripped from a dying Packard Bell Force SX20 somebody gave me.

This is a nice heavy duty case with a ton of screws (vibrations, I guess). It has a built in power supply with a floppy connector (surprise) and SATA power connectors, so I got a SATA to Molex adapter because I wasn't sure if I wanted to cut the original cables. It also has a case fan so I can do floppy things 24/7. There is just enough room for both drives.

I had to drill a hole in the back with a hole saw for the USB panel mount. Rather than remove the power supply from the case, I masked off the area behind the hole with tape to catch the metal shavings.

The original control panel sticks up in a triangle and is annoying. I tried to 3d print a flat black panel with the Greaseweazle logo for the hole where the control panel was, but it looked terrible and I was getting glue everywhere, so I went with a leftover iPad screen protector instead. It lays over the inside with a small block of wood to support it and some tape. Unfortunately you can't see the drive spindle moving back and forth.

Total cost < $100.
