What to do with this iMac

So I bought an iMac cheep as a refeb unit from a large enterprise, the problem I have is I don’t actually have planed need for this computer, so I turn to the fourm for some suggestions.

My ideas are:

  1. OSX build server (I had been looking at getting a Mac mini for this, but when life gives you lemo…)

  2. Plex server

The machine is a 2013 21.5” iMac core i5 2.7GHz with 8GB of RAM and a 1TB HDD. Since the machine was cheap, I am happy to spend some cash and spec bump the RAM to 16GB and replace the HDD with an SSD.

Well… I have a 2011 and removed the optical drive and added a ssd to it. Now I have 500gb on hd and 500 gb ssd. It works great for shared files, Plex, and even do some browsing on the internet. I have not found any other good use yet.
