Hi all! First time posting in here and bit of a noob when it comes to these sort of things. Please disregard or redirect this if there is already a thread on this subject. I am looking at upgrading my 27" imac mid 2011. Current specs are: 3.4 GHz Intel Core i7 16GB Ram AMD Radeon HD 6970M 1TB HD Ideally, I'd like to swap my current HD with an SSD while replacing my optical drive with either another SSD or a 7200 RPM HD. Additionally, I'd like to run 32GB of ram but I've heard mixed reviews about if this model can support more than 16GB. I know Apple officially says it doesn't on their website but I've heard of people doing it. Anyone's feedback is sure to be helpful! Thanks a bunch and I'm looking forward to being apart of the community.
