You could screw them to the wall to make shelves :) The photo is kind of what I was thinking would work though they used crates.
Here are some ideas for you
You could make shelves out of them. I've seen pet beds where they added a cushion to them. Add wheels or glides to the bottom, then a cushion and make a foot rest. Add legs and you could have an end table, either upside down or add wood or glass for open side up.

Lots of good ideas here;
Hi Angie: First of all, check to see if they have any antique value. If not, then you can put plastic water bottles in them, cutting the tops off first, fill with soil and have a small garden of herbs or small flowers or succulents.
Hi Angie, here's a few ideas that may inspire you....

Angie: maybe this will help
Hi Angie. You could use a couple of your cases in the bathroom. Roll up your towels and wash cloths and put them in your wooden soda cases. You could also use one to organize your make up and toiletries. Another could be used as shoe organizers. Another way to upcycle your soda cases is to use them to organize Christmas tree ornaments, especially those ornaments with sentimental value. Good luck Angie. I hope you are well.
Are they the kind with metal in them or just the wood boxes? If just the wood, you could disassemble them and use the wood for a coffee table.
stack them and make a bookshelf
I added the small cans from concentrated juice with contact paper on them (or paint). The lids from some deodorant cans snap right on to that. Hung on the wall and holds tons of sewing notions, craft items, hardware what every you want. You could also sand and leave plain wood and add items from nature like beautiful rocks, sea shells etc to display. Also keep in mind whatever you do to the case unless it is already in very poor shape, you ruin the value. Check them out on ebay and look at the price they are selling for!!!
You can use them for shelving for kids room and create a vintage vibe.
Make Tables, Benches, Shoe Storage, Desk, Stools, Planters, Store Garden Tools in them (long handles down) Fix on walls (inside or out) Take out insides and use as Ornament or Plant displays. etc. Make Toy Trundle trucks adding wheels or a dolls pram or a train!
