So I've spent so time researching this but still haven't found a definite answer. Does the 2010 5,1 Mac Pro use lidless CPU's? I know the 2009 8-core does but the 2009/10 4-core models don't. What does the 2010 8-core model use? Please don't say lidless!! ![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
