Purchased my 24-inch 2.93GHz iMac back in March. I haven’t found anything online, but I’m wondering if I can use my iMac as a monitor for another computer? A Windows-driven computer.
I know….I know….why? I’d really rather not run Boot Camp or Parallels and just keep using my Windows desktop outputting to the Mac if I can. Not enough room in my cabinet for the iMac and a separate monitor.

No, this is only a function of the new 27-inch iMac. And even then you'll need a bunch of adapters to make it work.
