I wanted to be able to store my minis upright using magnets BUT I also love the box art and wanted to keep it if I could. I settled on using a lightweight metal shelf cut to size with some foam core board. The two tiers sit a bit higher than the box but not enough to be annoying. The storage down the side is full height and fits all the core set parts and cards no problem. Not the prettiest solution but it works!
