oh I see, and that is so you can fit the Feser 360 down in the bottom of course.. right?

Nice. So far I'm liking my feser 360. My build it right below this one. I just updated the pics. Now the feser rad looks like it was meant to be there. but it's huge.

Anyways, keep up the good work.. I'm leak testing and will put my new system together tomorrow.
