I only have three systems, but generally I have two of them (Indigo2 and Fuel) connected via a KVM to use a single monitor/keyboard/mouse whilst my O2 sits in my cupboard - essentially in "storage". I never really have multiple systems on at a time, system usage depends on what I'm wanting to do at any one time.

Should add that my KVM for the SGI systems is also connected up to the docking station for my work laptop, hence whenever I'm working from home the monitor can be used for work alongside my other two screens. I like this as it means that extra screen on my desk isn't just for the SGI systems, it has other uses too.
