So I got this iMac 27" back in 2009... I think its a 11,1 model. Its got a 1TB HDD, and only 4 GB RAM. Wheres the best place to get a decent SSD at reasonable price, and RAM to upgrade to at least 16GB, probably 32GB. I'm using the entire Adobe CC suite of applications - any recommendations. and links to DIY upgrading or is it better to bring it to a mac specialist?
