Here here is a pretty thing:

Compaq

and:

Dell

Both are 1U keyboard/video/mouse trays using flat-panels. Probably laptop panels. These can save buckets of space in a rack. We're not that dense here, but at OldJob we were. I've had the Dell kind before, and have been somewhat pleased by it.

You really have to watch frequency response with the panels, and the laptop-decended ones are even pickier than the normal flat-panel ones. If you get stuck in a state where a video card insists on driving things at 85MHz, you really have no choice but to either reformat the server (icky), or haul in an old CRT and run through that. It can be a challenge. Especially if you have to deal with Sun equipment that insists on driving its video signal at 85MHz. Ahem. Fortunately, I don't have to do that at this job.
