OWC seems to have a great DIY video for doing this and I am planning to make the attempt, BUT does installing an OWC SSD in my July 2010 iMac cause any problems with the 3 year extended warranty? This may be an Apple question, but if anyone knows the answer, please let me know. I could not find anything about it on Apple's website. Btw, if anyone has experience performing this upgrade please let me know your thoughts, i.e., difficulty level, performance enhancements. etc. Thanks.
