I used this computer since I purchased it in late 2009. This January it froze on me, producing a mesh pattern on the screen (see photo). Fortunately, I had my images backed up. Mac OS Lion, 125 GB Ram, three One TB internal hard drives, complete legacy Adobe Creative Suite 6, Microsoft Office, and Sllver Efex Pro. Monitor not included. After repair it, with 128 GB Ram, it would be ideal for gaming
