Thanks! I got the wheels from Amazon (3/4" Expanding Stem Caster with Brake) for $63. It has a black rubber that expands out as you tighten it to the pipe legs. This causes it to have a night tight fit. Now, the rubber wasn't 100% thick enough so I added some Duct tape and that worked out perfectly.
And yeah, I'm glad for those LED light strips. They dont use up a lot of energy and they brighten up my office. I want to add LED lights to the bookshelf above my desk as well.
