Just wanna play a bit

[recan86]

I have an old tower that I don't use anymore. Thinking of mining just as a hobby. What can I mine that is easy to setup and lets me set and forget without doing much to the computer. I know coins aren't super profitable but I really would like to skip the talk about power or buying them directly. This is just a hobby. Any programs that can link me to pools which would help me do this? Any and all advice is much appreciated.

So you want a hobby that doesn't require you to do anything at all.  You don't want to have to research it, discuss it or really even think about it at all.  That's not really a hobby by definition.  If you aren't averse to reading, you might look here:

So you keep your Bitcoin wallet on this old machine?

Well you might try minergate - https://minergate.com/ 
There's a thread on Bitcoitalk.org about it as well - https://bitcointalk.org/index.php?topic=528848.0

  The software can automatically mine the coin with the highest exchange rate or you can pick the coin you want to mine.
