Apple does not have DVI to MINI-DP adapter (has a MINI-DP to Dual DVI, which works the other way around only). Also, you won't have audio. Audio for the new 27" ACD will go through the displayport connector (on the tech specs page only DP audio, but no USB audio is mentioned), so you'll need the latest generation MacBook or MacBook Pro, last-gen Mac Mini or alate 2009/early 2010 iMac for audio. 🙂
