This is a desk I just completed a few days ago. It is 58" wide, 24" deep, and 6" in thickness. The legs are welded (by yours truly) 2.5" steel tubing with a hammered steel finish.
It was build to accomodate a 61 key midi controller for a home studio. It includes matching monitor and speaker pedestals to save surface area (not to mention, they look pretty dang cool).
Walnut stain with a high-gloss lacquer finish. The keyboard sits on drawer tracks, allowing you to slide it out when you need it, and tuck it away when you don't.
