It's SO close. I'll have to make new power/reset buttons, and alter the mounting of the front usb ports, but it might just cram in there with a bit of trimming. The transformer will clear the bottom of the optical bracket but I'll still have to get some shorter capacitors. Mouser has the ones I'll need. I could even fit the dedicated 12v power supply in there too (green) and still have enough room for a fan on the side instead of the bottom (yellow).
