I purchased the 46'' H x 40'' W x 24'' D model recently - it shipped quickly and arrived a day earlier than expected. It was easy to assemble, and I like that it provides wheels if you wanted to replace the feet. After setting it up in the area where my "sitting-only" desk was, I discovered that the keyboard tray left a small area for my mouse. I have a full-size keyboard (17.5" W), so now I'm shopping for a compact keyboard with a numpad. I also ordered an Under Desk Cable Management Tray and a Single Monitor Arm Desk Mount. Once my monitor is on a mount and the cables are better organized, the whole setup will look great. I'm very happy that I'll be able to stand while working rather than sitting for 8-10 hours a day!
