... mount a 23" ACD above an (one of the new ones) iMac, and still be freestanding to some extent? The freestanding is a wish really. If it's fixed it's not a huge issue. The iMac will be in either a corner or not near a wall, so it needs to have an independent, non-wall-dependent mounting for both it and the screen. Holes can be drilled in desk no problems.
