It is a great case. The case has a feeling of quality missing in many new cases. So far I have built up 2 of them. Just remember to order the AT IO shield if you are going to use an AT motherboard. As far as assembly, it is a snap to put together.
Power supply is horizontal at the top in the back.
Built in mount and grill for second fan in the back. Fan mount in the front. Vents on bottom of left side panel as you face the front of the case. Replace the 4 screws in the back of the case with thumb screws and you have a 'no-tools' case. I have built two systems with it.
