Use 27" iMac 2010 as Monitor for 2008 Mac Pro?

[knicksplayer]

Hey guys!
Does anyone know if I'm able to use a 27" iMac (2010) as a monitor for an early 2008 Mac Pro? If so what cable should I be looking to buy?

Appreciate everyone's help.

Check out the comparability chart on this Apple Target Display Mode info page but it looks like you just need a Mini DisplayPort to Mini DisplayPort cable.
