IMac – What do I need to update a late 2012, 27″ iMac to SSD

imacssd

I know I need this thermal sensor from OWC.

I want a 2TB SSD disk. My question is: will any SSD disk fit inside a late 2012 iMac?

Do I need any special frame to make it fit?

I will be replacing the internal HD.

Not "any" SSD: SSDs come in a wide range of shapes and connectors. But any SATA 2.5" drive (in the same old form factor as Hard Drives) should work.

The tear-down instructions are found in iFixit. It is marked as "difficult". If it looks risky, you may want to just use an external SSD, connected by Thunderbolt, which should be sufficiently fast.
