I have a 2010 27" iMac, and I'm interested in adding a SSD to it (keeping the regular HDD inside too). Obviously it is easy to buy an SSD...but I'm not confident I could handle the installation. Has anyone ever had a local computer shop perform this upgrade for them? I was thinking of calling Micro Center or Best Buy. I know OWC has their turnkey program, but I'm interested in doing it locally instead of shipping off my baby.
