As mentioned in another thread I've got computer servers in the basement which I want to rack mount for a more professional look. I bought a "25U" rack which is 4 feet tall, but I wanted to raise it off the floor for a more convenient height and contain some UPS units. So I broke out the Festool tools and built a box on wheels out of prefinished maple plywood. Eventually I'll probably add maple side panels to give it a more finished look.
