iMacs

I've never used one, only used a Mac Pro, does it have a base unit?
Or is all inside it's screen?

I have no idea. xD

Its all inside the screen, well behind it. All thats external is the mouse and keyboard.

Thanks! :)

Plus it's rather small. It's about the same thickness of a normal LCD screen without anything inside it.

Ahah thanks all. :)

Depends on what mac you get to the configuration of the hardware.
