The frame was going to be out of square stock, though that may change, been looking at doing parts of the case with rivets, I assume with solid bars it would be too thick to use rivets, but not angle or hollow stock. After looking at some materials the size will have to change, seeing a 2' cube irl is alot differnt that on paper/comp so I am working on what will have to go inside then get back to the frame, I have found several good options from posts and suggestions.

To my above post about the ducts for the radiators here is a quick mock up picture of the idea.



The plan would be to have 2 of these in the bottom half of the case.
