Budget farming is the best way for a person to boost their output in a DC project, but even a relatively cheap farm can get expensive when you start factoring in multiple monitors, keyboards, and mice. KVM switches can help reduce the cost, but at anywhere from $100-$300 for the switch, depending on the quality and size, and $20 or better for each set of cables, even this option can begin to exact a toll on the wallet. However, assuming all of the machines on your farm are connected to a network, there is an excellent alternative that will not only give you all the functionality you need, it also has another benefit that makes it almost irresistible to the budget farmer - it's FREE! The name of the alternative is VNC.
