Thanks to geek technique for inspiration, they do have instructions, but not an example of if a 32 gig card would would work, and indeed it does.
Step 1: So you have an Ipod mini...
Step 2: Get it open without a scratch
To do this, we're going to use hot glue as a 'handle' to get ahold of the plastic without damaging it. Sometimes a little dot of glue applied and let cure is enough, sometimes you have to glue something down to the piece to use as a handle.
For me the bottom was easiest, add a dab of glue, let it cool, pry it up gently, and put a screwdriver under the plastic to keep it up.
Also, I would be careful with a high temp glue gun, they may or may not melt or distort the plastic, I didnt try, and high on one gun may be a lot higher then another, so dont say you weren't warned if a high temp glue gun melts your ipod and eats your first born.
For the top, I had to glue a screwdriver down to the plastic piece and use that to lift off the cover.
