2.8GHz Intel Core i7 CPU 12GB 1067MHz DDR3 RAM (upgraded with Crucial memory) ATI Radeon HD 4850 512MB graphics card 27" display, max resolution 2560x1440 1TB 7200rpm hard drive SuperDrive (CD/DVD burner) Bought brand new from Apple store in summer of 2010. Have all original packaging, magic keyboard and mouse, and throwing in magic trackpad (or should I sell that separately?). Was about $2200 at purchase, I'm asking for $1500 on craigslist. Reasonable? Where else should I try to sell it?
