Setting up / using Apple TV 1st Gen.

Hello Everyone,

I have a weird question I guess.. I have a first generation Apple TV in perfect condition, that has just been sitting in a drawer since I got newer models in later years.

However, these days having a little more time on my hands, I am fixing up everything I can, trying to put everything I own to good use, and so I was planning to set it up as a little entertainment device serving a guest bedroom. The problem is, it does not even show up in iTunes any more!

Doing a little research online, it looks like to me, since this model was discontinued, even the support ended, and so I ended up with a perfect condition brick??

So, maybe the Community here could help me:

1.) Is there a way, to get it running again as an iTunes server? (I use a Mid-2011 iMac, running the current MacOS Sierra 10.12.3, and the latest version of iTunes 12.5.5.5)

2.) If it can not be used for iTunes any more, what other useful stuff can I install on it?

3.) Does it worth upgrading it in any way (I mean with an SSD drive, etc.)? I do have a 4th Gen. Apple TV for the living room.

Thank you in advance for all your input, it would be of great help!
