Last week I got the Mac Mini’s big brother: a 2012 iMac 21.5”. The seller packed it so well I thought there was a mistake and they sent a larger model due to the amount of packaging.
Currently it has an i5-3330s, 8GB of memory and a 1TB Fusion Drive. When I received it, the SSD and hard disk of the Fusion Drive were separate - had to research how to combine them. The drive is faster than I expected it to be, but this is the first Fusion Drive I own so there wasn’t any sort of expectation as to its performance.

As is the case with cheap iMacs on eBay, this one has a couple of chips on the right side of the glass panel and a crack in the glass at the bottom right corner. The chips are covered with a piece of electrical tape, and the crack isn’t noticeable if you aren’t looking at the screen at an angle.
I have plans to upgrade it, but will wait until the sets of adhesive strips arrive. I have 16GB memory and a 1TB SSD to install, and have ordered an i7-3770s processor that will arrive in about one week.
One question I have is if the hard disk is replaced with an SSD, does anything special need to be done regarding a thermal sensor? OWC upgrade kits include a cable that appears to do something regarding the sensor, but I haven’t had a “recent” iMac before.
