Wizard currently sells a nice convertible free-standing unit - 2 different angles or mount it to your wall (I think, I not as familiar with the stand design as our sales team).
At the shop I worked at 10 years ago, we built a simple matboard storage unit about 33" high to store full sheets in horizontally, and then just placed our Wizard on top of that, leaving enough room on the end for the monitor, keyboard and mouse. The 41" of depth gave a pretty good angle on the CMC, but you still had to worry about the occasional drop-outs.. really though, warped matboards are the most problematic in my experience as they tend to bow out when cutting.
At the shop I manage now, our CMC is mounted to a pair of 4x4s running from the floor to the ceiling about 2 or 3 inches away from the wall. I didn't ask why, but I'm assuming that the previous owner did that because the neighboring tenant was complaing of the noise (its a 5000 - when that thing plunges you can feel it
). But its mounted at the steepest angle and doesn't take up that much room - we have the fridge and a shelf unit to hold the PC and stuff...
As Baer said, we are looking at another stand design, but nothing is concrete about it yet.. I'll hopefully know more about it next week. I'm pretty stoked about it though, and can't wait to get one for my shop..
