Furniture or Storage units for External Hard Drive Enclosures?

This will hopefully be a real easy question for someone who has it; and probably insanely difficult for anyone else.

I am looking for, some kind of storage unit, that can house a large number of Western Digital MyBooks (external Hard Drives in their own enclosure).  I've got about 24 of these right now, half of which are USB 2.0, other half are 3.0.  They all require their own power, plugged into an AC outlet; which means each unit has two cables coming out the back of it.  Since the number of these drives has grown so large, I am trying to find some kind of wood or plastic unit that is designed to hold them all.  The ability to hold some of them, if not all 24, would still be preferable to housing none of them.

Before I start to plan out some dimensions and build the thing myself out of wood, I was hoping that maybe someone knew of a product that is designed to hold all these things together, maybe provide some air flow, and/or have a locking door to it, etc.  So far, whenever I do a search for MyBook and the word storage, well, all you get is the MyBook because its a data storage device.  Mannn...


Thanks.
