I'm thinking of possibly selling my 2009 iMac, and I'm wondering what an appropriate market value is for it. It is the late 2009 27" iMac with the following specs: 2.8GHz i7 Radeon HD 4850 512 MB 8GB of RAM (4x2GB) Optical drive replaced with 128 GB SSD (Crucial) Hard Drive replaced with 960 GB SSD (Crucial) I currently have the OS installed on the 128 GB SSD, and all the user accounts on the larger 96O GB SSD which works really well. It requires the use of HDD Fan Control. Everything works great but I'm looking to upgrade to the 5K iMac when it is released. Depending upon the answer I may just keep this one around for my kids homework as well.
