5 out of 5 eggsNice Case for the Price

Pros: Decent Size for a Mid Tower, Solid Construction, Aesthetically pleasing, and decent airflow.

Cons: Cable Management is extremely difficult with this case. the Front Three LED's have a white Male 2-pin plug that doesn't go to anything on my ASUS Z-97 Motherboard, or PSU, but I am working with NZXT on that issue. Maybe I just can't find where it goes, or don't have the connectors for it?

Other Thoughts: With this being refurbished, and having done my research I knew cable management was going to be tough, so I can't knock an egg off for that.

And as far as the Front 3 LED's go, can't knock an egg off for that either as it may just be i can't find the connection, but i am working with NZXT to resolve the issue.

5 out of 5 eggsTotally cool case (pun intended)

Pros: Its very cool appearance and has cool cooling too! I really like it. The only think I would add, is that the inside is lit very well. If your looking to have a really lit inside, I would still get this case, but add an light.

Cons: extension card retainer tabs are not the best. Use caution or they will break.
