I'm ready to buy an iMac but one thing is holding me back. I really want an SSD, but can't wait 4-6 weeks. Is there any definite confirmation on whether an aftermarket SSD install is possible? Is it just the same as the 2010 model (requires a bracket etc.). Is doing this king of surgery on your iMac dangerous in any way (as in damage the iMac, void warranty etc.)? I was thinking of getting an Intel 300GB 310 series SSD, good choice?
