Dual 5.25" Drive Bay Accessory Box, Do They Exist?

I am looking for a storage box that can take the place of two stacked 5.25" CD drive bays. I need somewhere to put my bowl/grinder/tools of the trade that is hidden but easily accessible. My grinder is too tall for a single slot accessory box so I need a double bay box, if there is such a thing. Endless Google searches have yielded nothing. Does anyone know anything about a product like this?
