How does a canopy work with a HOB filter? I've been looking into DIY canopies, and I'm not sure how it accounts for that thing sticking out of the back.

Depends upon the canopy...most, especially for small tanks will make some accomodation for a HOB, but you'd want to verify the height of clearance in the back of the canopy vs. your HOB first.
