The key is that these PC's will never have dedicated monitors and keyboards.

I've heard of KVM over IP, but that sounds nothing more than RealVNC or something equivalent.

I want to be able to do everything from setting up PC BIOS to running DOS or some LINUX boot disc.

Right now I'm using Belkin OmniView Pro2 KVM's and really want to eliminate this cabling.

Also, I have no budget (!) so I'm in the used eBay market.
