Use my iMac as a PC monitor?

[The JTizzle]

Got an old PC I need to use for some work stuff and wanted to save on some desk space and skip the 2nd monitor. Been reading conflicting reports on what I need to do it. Anyone done this themselves and can tell me what I need to get to make it go.

Using a 27-inch iMac (Late 2009 or Mid 2010) as an external display
