There are extension cables for each type; in the case of input devices it's not going to be too great a problem, but with analog monitors the risk of "ghosting" skyrockets with increasing distance. In theory, if your monitor's cable is of a high enough quality and the extension cable is well-shielded and very high quality, you might not have too great a problem. If your monitor has a long enough cable (aka the VPR Matrix 17" with a 3-meter cable), you can hopefully get away with using only one extension (usually 2m in length).
An alternative approach might be to look into making your computer quieter, although that doesn't help the space considerations.
