Yesterday I described the MPG Pro One™, a maxed-out iMac 27" for those seeking the highest level of performance for photography, video, sound, etc. The MPG Pro one is built to MPG specificiations by OWC. The MPG Pro One is maxed-out with dual solid state drives, 16GB memory and your choice of a third drive. It also enjoys special attention, including a custom system install, certain best-practices configuration, and an 8-hour rigorous burn-in test of memory and hard drives, nothing but rock-solid comes to your door.
OWC has announced an a la carte option for upgrades to the 2010 iMac 27":
Turnkey professional installation service offers customized configuration of Mid 2010 27" iMac with high performance eSATA interface option, OWC Mercury Extreme Pro SSD up to 480GB, hard drives up to 2TB, and/or OWC Memory Upgrades up to 16GB complete with shipping and warranty starting at $169.
This program is a real value: OWC does all the delicate work (while I am at ease upgrading a Mac Pro, I am not comfortable working inside an iMac). If they break it, they buy it!
