Excellent case. I've got two and have had ZERO problems. For those whining about the HDD trays, all I can say is that I've had no issues at all with them on either case. And all the bays are in use, and I've done multiple HDD swaps with no issues.

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

Every once in a while, I like to get out of the power supply testing lab to take a look at a computer case. Some have been big, others have been small. Today, I've apparently come downtown to review a skyscraper, complete with seventy-five floors of residential living space.

As far back as i can remember myself i always liked to have my systems installed inside full tower PC cases not only because i really wanted the extra space so i could mount hardware with ease but also because they offered the largest number of 5.25" drive bays possible something which made it very...
