I just got a new computer, I was at my grandma's house today. and her neighbor was walking out to the trash with a mac pro, I walked over to her and asked her if she wanted to get rid of it, and she said yes,
I get the computer home, hook it up and it works PERFECTLY!
Here are the specs:
2x 2.8 GHz Intel Xeon processors
4 GB RAM
Mac OSX 10.7.4
