Price History (Excluding Tax & Combo Deals) History:


from completed build Athena AMD Balance Gaming build

Pros: The case is a little on the cheap side, depends on the price you get if <$60 I say its worth it, but not over, just save $20 or $30 more and get a better case.

Its got good airflow with space for 140mm fans in the front, altouth getting 140mm there would be a bit of a pain cause of the space but its doable.

Its a decent size so it can fit a CM Hyper 212 Evo with a couple mms to spare.

Has dedicated SSD slot (but you need some force to set the ssd in)

Has a good size back plate cut out and cable management cut outs

Will fit very large graphic cards and psu

Supports 120mm fan in the bottom (if your psu is small)

Subjective, but I think it looks cool

Has a windows to show ur work of art :)

Cons: First you have to make sure to route the CPU power cable BEFORE setting the mobo or it wont fit. The cut out is too small for the connector to fit, so pass it before you screw the mobo in place. Once there you can pull the cable though is a little tight.

Also I recommend you plug the cable right there and then, otherwise you might have a hard time trying to plug it specially if you have a big air cooler like I do.

The "air filters" are useless, their are more like a mesh with really big holes. I live in texas which is kinda a desert so there's a lot of dirty in the air, I have only around 3weeks with this build and I can already see dust inside it!! but with 2 fans pulling intake I guess that was bound to happen.

Also these filters are a pain to remove. The one on the top is not realistic if you install fans or a radiator since you will have to remove them to get the "filter" off. The one of the front is easy enough bur you need to take off the whole front. The once on the bottom for the psu is also a pain to remove. I suggest you do it with the system off and cables unplugged so you can till it more easily.

Before buying the case I saw reviews complaining that the paint comes off very easily its true. You can see this if your not careful with ur screw driver or while installing the psu.

Also there are no grommets for the cut out holes for cable management, not a big deal but worth mentioning.

This might not really be a con but, the windows is kinda big, consider this before getting it.

I tried to hide my PSU cables but since the space on the side panel for cable management is not very big, hiding all the cables is not easy you will see them cause the big windows doesn't cover not even the hard drive cages.

Other Thoughts: Overall I think the case is good looking and has an attractive price, but is kind of a pain to work with and wont help keeping ur system clean, if this is not a deal breaker I say go get it.

The side bevel is nice for cable management

from completed build Red and Black

I like this case, good metal build quality, helps with cool temps, but the cable management in this thing is terrible, so if you're a stickler for that, don't recommend this case.

from completed build LARRY First build

Very impressed with this case. It has a bit too much gamer-flashiness but all in all it looks nice. Lots of space for additional fans, and a nice window. I personally don't use the window, but who cares, it's there. I don't think I had a single problem when putting the computer together, other than the screws for the pci-e ports are thumb screws, but are impossible to unscrew the first time without a screwdriver.

from completed build First ever build

The case is great and durable for me so far. I have zero complaints.

from completed build Mid-High Range Gaming PC

Nice case. Has a nice window and enough drive cages for my needs. It also has nice rounded edges so I don't cut myself. It feels very sturdy and the window seems to be fairly scratch-resistant.

Airflow is great and there are many fan mounts. The included fans are mediocre. The LED fan certainly has a nice look though.

However, the dust filters are not easily removable and replaceable. They are just flimsy sheets of mesh that can be a pain to put back. Also, the cable-management holes are not grommeted and I would like to see more room behind the main compartment so my cables wouldn't push against the side panel. Other than that, it's a great case.
