Other World Computing (http://www.macsales.com) says its OWC Turnkey Upgrade Installation Program for the mid-2010, 27-inch now offers iMac owners the option to upgrade the hard drive to a 3.0TB model. That’s a 50% storage capacity increase over the 2.0TB factory option.

This new storage capacity option joins existing upgrade program choices:

° Adding up to three OWC Mercury Extreme Pro SSDs for up to a total of 1.44TB capacity; up to 5.5X higher than the factory SSD option;

° Adding the first offered eSATA port option for an iMac, and/or adding up to 16GB RAM with savings up to 81% versus factory options.

The turnkey professional installation service program offers multiple configuration options starting at US$169 with a 48-business hours or less installation turnaround and includes complete shipping options along with OWC’s warranty coverage.
