Hi Jody: If you are looking for something quick and with storage, it might be just as cheap to buy a small dresser or night stand from a thrift store. Just a suggestion :)
Jody: I just saw this on tv. Maybe you an use your wood and do this:
I would think you would build similar to a coffee table. Leave front and back open for air and access. Purchase screw on legs would be the best method imo. Then make the flat surface out of the barn wood. You could affix to plywood for a frame if you don’t have tools to join together.
It all depends on your woodworking skills and tools. It would just be a box.
We put our mini fridge on a shelf my husband made out of store bought metal brackets and a piece of plywood.
