I have just done this with my CMS PRO60-II/i (not a 3.5" half-height).
My understanding is that 2 3.5" HDs can be put in a II.

I understand the drives both go behind the floppy bays.  They would
probably fit the opposite of how they're now installed.

Lots of mail orders sell conversion kits from $99 to $199.  No idea
how good they are.

I'm using SilverLining.
