Most of the people I know they didn't updagraded their Mac Pros ever in 3 to 6 years of use. I heard people upgrading memory, replacing discs, but the rest it should be intact. The Mac Pro is a nice machine for people who won't upgrade in 3 o 4 years, even more and still having power.

If they didn't release this, I would continue with the idea of making my Hackintosh but this new baby is nice.
