I feel like it makes sense to work with convection too and pull air out the back of the case like you said. It sucks that the radiator will be pushing air out the front of the case too, but honestly the case is very very open so I think I will just have to see how temps look after running a bit. I'll save advanced mode for the next build but thank you for the idea! Knowing that the ends will need to be straightened I printed the center slice a few millimetres oversized in its length to make up for the material I plan to remove. Hopefully I can straighten the ends and not need shims! Joining the three pieces is three more than I want to join since I'll have to bondo and smooth them to look like one. I'll let you know how this goes!
