Have you verified the inner height of the drawers?
I once almost trekked across town in a blizzard to pick up some free drawers like these that were used for something big and flat (architectural drawings?). Fortunately, i was able to get the inner height measurement and realized that they were too low to accommodate a rack of chips.
PSA to everyone -- just make sure to double check the clear height inside the drawers, for whatever your storage needs are.
I work in civil engineering, and have seen flat file cabinets like this for plans throughout the years, and I can say most drawers are shallow. (They're designed to store large sheets of plans stacked, but *might* not have enough clear height to fit chips in plastic racks.
