I'm running an early 2009 iMac which I upgraded myself to an OCZ Vertex SSD. It wasn't too hard to do so long as you're careful and methodical. I'm wondering how easy it would be to upgrade the new iMac as I don't know yet whether the glass pops off the same way as it did with the previous generation. I'm planning to upgrade to the new model and would like to put my SSD in there so I'm hoping it's not too difficult to get to the HDD bay.
