This is where I do things like this. It looks like a mess, and that's because it is. But it is effective. Both halves of this setup are Anthrocarts, on wheels, and I can swivel one or the other around as convenient. In fact, all of the furniture you see in these pics are Anthrocarts, which I picked up (relatively) cheap at a local used office furniture place.
Below the work surface, which is at convenient stand-up height, are two recessed shelves. I store test equipment and parts bins there.
