I did quick power up test it works. Having never used a mac pro it took me 6 minutes to figure out how to use the dvd player. LOL! It is quiet. The picture is better then with my mac mini. It is fast. I dropped in a pair of ssd's made a raid0 cloned the oem hdd to it and it crashed would not boot. It allowed me to use each ssd alone. corsair x64 types I will need to go to their forum to find out why a raid0 doe not work. I got xbench scores of 340 vs 230 with my mac mini. I will be busy until monday. I will try to figure why the raid0 crashed on monday. I am running it via an intel x18m 80gb ssd. I have two of them I will try them in a raid0 on monday.
