I've installed the power supply, made by Enermax. The PSU has a large fan on the bottom, and the cage for the PSU is in the bottom of the case. Initally I installed it right side up, but realized that airflow to the fan was very restricted (a 1/2" high chamber open only on one side), so I yanked it out and flipped it over.

I love this case. It actually came with a manual (another first for me)... has pull-out drawers for the hard drives - see the two rings in the lower right.

Next step... the motherboard.
