I used to just store them in the original anti-static buble wrap and shipping box that they came in. But then it got ugly and nothing but clutter.
So I went to office max and found a big box that would allow enough room for padding and anti-static bubble wrap or bags.
They were overpriced as always at Office Max. But couldn't find any other place that had decent boxes. Reversible if you want box color or all white color.
Did some custom artwork details to them and have them shelved.
