Oh, it's back together, but no screws. Actually I did not snap the bottom into place, I left a small gap. This way the external fan has more escape room for air volume.

Here's a link to the stupid thing. It's cheap enough, and good, other than the fan. I'm sure there's another way to address the problem, this just happen to be my way. Lots of ways to skin a cat.

I did download an ap to measure CPU temp, and it's fine with just the external fan on it.
