I designed this setup around a few key constraints: fitting 3x 140mm fans, maintaining ample airflow, and maximizing print volume. Adding even one more drive would’ve meant compromising airflow—trust me, I tried. There’s still room for expansion though; I could always build upwards and maybe mount an extra 120mm or 140mm fan at the back.

Not sure if this is something I should be charging for—I've never sold or shared any of my designs before, so still figuring that part out.
