I am selling my Mac Pro 3,1 tower it is an 8 core model with 8GB of RAM (supports 32GB) and 2 brand new 1TB Western Digital HDDs (can support 2 more). It is running OS X 10.11 El Capitan. Includes the wired keyboard with number pad and a mighty mouse. It was used it my recording studio and still works amazingly well for audio production and video editing. $400 cash firm or will consider trading for a 2013+ MacBook Pro.
