I have a custom built SandyBridge PC and I was thinking of using the 27" iMac as it's monitor. But I can't do that with the current iMac, correct?
 
Both 2010 and 2011 27" iMacs can be used as external monitors. But will require the proper adapters to accept signal from PC or PS3 or other non-apple sources. You won't be able to get full resolution though. I believe it's 720p. You only get the full resolution if you're connecting to another Mac

I know you can for 2010 but what adapter for 2011?
 
The 2011 requires a TBolt equipped source. Only the 2010 can take a DisplayPort source. Kanex is supposedly working on an HDMI to TBolt adaptor but availability and pricing are not out yet.
 
Those new thunderbolt plugs still function with MiniDisplay Port products. So it should just be a regular adapter like what's used on the 2010. Link below to my personal favorite.

Nope. Apple has disabled that.

iMac (27-inch, Mid 2011) computers do not support Target Display Mode via Mini DisplayPort cables. iMac (21.5-inch, Mid 2011) and iMac (27-inch, Mid 2011) support Target Display Mode via a Thunderbolt cable, when the source is another Thunderbolt-equipped computer.
