5 out of 5 eggsI like it

Pros: Looks nice, has good ventilation. Case fan is very quite.
Two USB 3.0 ports in the front (and one USB 2.0) can be set to do charging (that is a mobo setting). The USB 3.0 connector fits the mobo connector (20(-1 that is not in use) pins connector).
When I installed the mobo, everything fits fine. The holes are raised and there is no need to install raisers. The DVD/CD and hard drives slides into a rail and are held with a clip which is very comfortable to handle.
There are enough screws from all kinds for everything you need.

Cons: Also, it is convenient to have audio and USB connection in the front near the top. If you plug something into them, the wires falling down and may stand in the way of the DVD tray and require holding them while closing the tray. I saw other cases in which the audio and USB connection are in mid case, below the DVD tray.

Other Thoughts: When inserting a hard drive, the cables may stand in the way of the case cover. The solution is to turn the hard drive the other way and slide it into the rail with the connection at the bottom.

5 out of 5 eggsNice Case

Pros: I ordered and received 2 of these cases in good condition
and the finish i was looking for, without the gloss-finish
which i disapprove of in the 1st place.. It has lots of room
for air-flow (7 case Fans) and easy installation..

Cons: Just a heads-up here,, remember to install the Mobo FIRST
before installing the top fans, or you will have some minor

Other Thoughts: Otherwise you will have a solid case that will last for many
years to come.. InWin manufacture great cases..

4 out of 5 eggsLike a Boss

Pros: Great case, cable management, sturdy and well built, mesh in side of case looks sweet with case lighting.

Cons: paint scratches with relative ease, and some cables in case would be far easier to manage with only 1-2 more inches on them, had to get a bit funky with the USB 3.0 header for front of case

Other Thoughts: great for the price I paid (sale $54.99) only reason case is 4 stars is due to an imperfect but great design. 5 stars reserved for perfection

hope this helped :)

4 out of 5 eggsGood case for $39.99

Pros: Fairly sturdy design for the price. Has plenty of space for hard drives, and they clip right in. DVD multi's etc. fasten without screws as well. Plenty of space for extra fans. "Front fans clip in". Supports H2O cooling but I don't know who would be doing that in a lower end model like this.

Cons: Not very cool looking as is. Plain black, Unusual shape to front of case in my opinion. The 7 120 mm fans this supports is a little overkill and obviously not the most efficient cooling solution. Although for the price I paid it has better cooling than most. The front audio ports on mine don't work very well, "Or" it could be the connector on my motherboard, don't know 4 sure.

Other Thoughts: Adding a few blue LED Fans to this setup will make it look much cooler, "Power LED is blue", and perform cooler as well. My 560ti rarely goes over 70 c with it's fan on auto setting. $10 bucks or so for a couple blue led fans, " clip one in the lower front 4 sure", and u have a sufficient and neat looking setup at an affordable price. "Check out the higher end In Win cases cool designs"!

5 out of 5 eggsNice case

Pros: Spacious, light, easy to install everything. Room for 7 120mm fans, and the front two don't require screws (see other thoughts). Hard and optical drives are also easy to install.

Cons: I really miss having a removable motherboard tray, but there's plenty of room to work in the case (helps having the PS at the bottom), so it's not really a problem with this case. Front panel is kind of difficult to click in completely, because of the way the optical drive covers are attached. Side panels can also be a little bit tricky to line up correctly, and they're really thin so they can easily be misaligned.
USB 3.0 cable from the front panel is 20 pin, so you may have trouble finding a MB or add-on card that supports it (there's an adapter available, but that can also be difficult to find).

Other Thoughts: Took me a minute to figure out where the front fans were supposed to go, as there is no way to screw the fans in, they just pop in and are retained by plastic clips. I was worried about vibration noise, but they hold pretty tight.
I'm not currently using the SSD carriage, but it is there if you want it.
This was not for a new build, just moved from a different case for more room. I'd buy another one.
