There's a right way and a wrong way to go about something like this. You can't design a good setup before you even know how standing most of the day feels for you. Get a good adjustable stand, don't skimp on "accessories" like gel mats, ease into it, and above all <i>listen to your body</i>. If you're uncomfortable, sit for a while. If you're sitting too much, try standing differently next time - e.g. monitor/keyboard higher or lower, feet closer or further apart, shifting weight. Your ideal standing position/habit for work might not be the one you've been using in other contexts. Maybe standing for long periods, in a body shaped by long years of not standing longer than absolutely necessary, just isn't for you. I hope more people realize the benefits of standing more and sitting less, but even more than that I hope nobody hurts themselves trying.
