Beware the iMacs of March?

The new Mac desktops that Apple (AAPL) had been expected to debut at Macworld may finally be announced later this month. According to the latest rumors, anyway. Sources tell World of Apple that Cupertino is planning a special event on March 24, one that will likely introduce updates to the Mac Pro, Mac mini and iMac. All three are overdue for a refresh, particularly the Mac mini, which was last updated in August 2007.

UPDATE: Hardmac is now claiming these new machines could be released as soon as tomorrow.
