Car Stereo CD Player for the Shop

I wanted to get some music in the workshop but did not want anything big and bulky.  Ideally, it would be nice to get wifi and hear music from the computer but inside the garage does not get my wifi signal.  I will have to run a cable out there sometime.  Since I already had some nice speakers, I decided to just get an inexpensive car stereo and pair it with an old computer power supply.  Then I made a dovetailed box out of pine and put it up on a shelf I made.
