All, I have a base late 2013 21.5 iMac and the stock 5400RPM HDD is a dog. I recently snagged a a great deal on a 500GB Samsung EVO 850 SSD. I want to throw that sucker in there. So my questions are: What type of 2.5/3.5 conversion kit do I need? Just the brackets or additional wires? Will I have a problem with the thermal sensor for running the fans? I see that OWC sells these for the 2011 iMac but no mention of it being a problem for the late 2013 models. Any additional tools or information I need to know of? I understand the risk and pita to tear these apart. ifixit has me covered and I'd be doing it with someone that has done this sort of thing before. I thought about slapping the SSD into an enclosure and running it through TB/USB3.0 but want a clean setup. Anyone want to convince me otherwise?
