=== Temperature ===

After running iozone, and being up for a few hours. No HDD sleep, but it is nice to notice that it does power down the HDDs, and spin them back up as needed.

Please note that these are Sun Hitachi Deskstars 7200 500GB SATA-2 Hard-disks, sitting on top of my MacPro. I will actually use Green, slow spinning hard-disks personally. The case itself has good airflow though.

I sure wired the SATA ports sanely :)
