I'm looking to breathe some new life into my late 2009 27" iMac. I'm too tempted to get a brand new iMac, so I figure if I can slap an SSD in my old, it'll save me a couple thousand dollars in terms of added performance. So...can anyone recommend an SSD that will work in an iMac? Looking for about a 256GB one. Additionally, I would be doing this project myself, so a pointer to easy to follow instructions would also be appreciated. I do have extensive PC building experience, so don't worry Thanks for your help and suggestions in advance.
