Nifty Home Products 24 Coffee Pod Capacity Storage Drawer Rolling K-Cup Holder, 12.75x8.25x3, Black

Will the keurig b145 office pro fit on this? I would like to buy it for my mother and she lives out of state so i can not measure her machine. Thanks

Are these drawers stackable?

What is the difference in the 6470 and 6475 model?

Does the whole unit roll out with coffee maker on top?
