Hi, I have a cMP 4.1 that I'm interested in selling, but not sure how much I should ask. Specs: Quad Core" 2.93 (Early 2009/Nehalem) 12 GB RAM 1 Apple 5770 2 Apple GT120 SSD adapter for stock drive bays. Several HD's, including a 1 TB apple drive. I also have a 30" Apple Cinema that perhaps should go with the MAc. Any advice? Thanks.
