5 out of 5 eggsSolid Purchase

Pros: Cable Management - Front port and button cables come pre-routed through a cable cage (Although the power and USB cables were tucked into the back wall and had to be pulled out). There is also additional space in the embossed back wall to stuff extra cables.

Great Ventilation - Although it only comes with one fan, there's room for two in the ceiling, two in the front, and two in the side. Even without buying extra fans, these ventilation spaces are fantastic.

Awesome Design - The ridges on either side of the front panel look even cooler in person. The honeycomb front, side window, and all-around vents combine to make a great looking case!

Cons: Only one fan - Wish it came with more than one initially

Smallish - Not a problem if it's for an entry or mid-level machine, but don't expect to fit any 3-fan GPU's in here.

Other Thoughts: Overall great buy, I would recommend this to anyone building a PC for under $750. If you're buying some extreme components, get something bigger to accommodate them all.

5 out of 5 eggs

Pros: Very nice looking case for the cost. Pretty good wire management, plenty of HDD slots and great cooling options with a nice little windows on the side that isn't too gaudy.

Cons: None that I can see so far!

Other Thoughts: The top plastic part popped off a little too easy for my standards but nothing worth conning.
