There is a nifty device that does what you need. It is a floor-mounted
articulating arm with mounts on the end for keyboard/mouse tray and an
LCD monitor. Found it in a magazine once and filed in grey cells for
future retrieval.

I would caution against having your monitor so low you have to peer
around to look at it. Sounds like a neck injury waiting to happen.
