They even give you a extension cable to connect CPU power because the PSU is a long way from the top of the mother board.

Everything

The price; but I guess you have to pay for quality

This case has room for everything, can be expanded for 15 hard drives while still having room for 4 Blu-Ray drives! New, it's a bit expensive, but if can find it used for $220 or less, just buy it. Any missing components are relatively inexpensive to buy directly from Corsair.

Lots of room for many / large video cards and drives Excellent build quality Nice looking Dual power supply possibility No tools needed to change drives; open case; etc

It's heavy

excellent packing AAA+ service

We had to wait quite a while before the Corsair Obsidian 900D was released, but it's finally here and it was definitely worth the wait. From the get-go we say that this has been an intriguing experience.

This is a large and expensive design that features hardware flexibility few cases can match. For drive flexibility it features three removable bays that allow installation of up to nine 2.5/3.5 inch HDD's and SSD's. It also has four external 5.25 inch bays to round out drive options.
