Two options Both are 21.5 imacs in really good condition: $375 for: Late 2009 iMac 21.5" 3.06 GHz Processor 16GB RAM 500GB HD NVIDIA GeForce 9400 256MB Mac OS 10.11.6 (El Cap) Serial number QP0101FT5PK or $550 for mid-2011: Software Yosemite ILife 11, Office 11 Adobe Master suite CS5.5 Final Cut Pro Windows 7 The iMac Quad Core 2.5 GHz Intel "Core i5" I5-2400S (Sandy Bridge) processor with a dedicated 256k level 2 cache for each core and a 6 MB shared level 3 cache. In lieu of a system bus, it has a "Direct Media Interface" (DMI) that "connects between the processor and chipset" at 5 GT/s. 8 GB of RAM (1333 MHz PC3-10600 DDR3 SDRAM), 500 GB (7200 RPM) hard drive, DVD+R DL "SuperDrive" AMD Radeon HD 6750M graphics with 512 MB of dedicated GDDR5 memory. my Biggest concern is buying the $375, and it being a 2009 model, but for ~$175 more I could have a 2 year newer model? Thoughts?
