Performance -
Like most things that I review I tend to look at more than one aspect of performance. For me a case has to offer several things before it makes the cut. One of the first things it has to do is be easy to work with. It can be the best looking case on the planet, but if you cannot get your parts installed properly well then it is useless. The next thing it has to do is keep your parts cool this is the air flow test. Lastly (in my book anyway) it has to look good.

Ease of Build -
One of the things that comes with a larger case is usually a much easier build. The Level 10 GT has a good deal of space and as such it gives you room for good cable management and also to make sure there is good airflow. The 5.25-inch drive bays are tool-less so all you have to do it run power and a data cable up there and then lock the drive into place. The HDD bays are very simple to work with as well and you can get them working in a matter of minutes. We chose to use the Asus Rampage III Black Edition Motherboard for our base build.  This is a slightly oversized motherboard and has more features than we will ever need. For peripherals we are using the Thunderbolt’s KillerNIC interface, but not the audio. We have an Asus Xonar Xense to keep our ears happy. For graphics we are looking at a FireGL Pro 8800, this powers the triple-display Eyefinity that we have been working with. As you can see from the build images everything fits with room to spare. The left over cables lay down in the bottom of the interior with room to spare for airflow while we were able to run the majority of the bulky cables behind the back plane in the space that Thermaltake put there for this.  This is one of the cleanest builds that I have done (I do not spend a ton of time on cabling for these reviews) in the short time I spend on the build. If I am able to get things this clean in about 30 minutes, imagine what can be done with some real time put in.

Air Flow -
With the four fans in the L10 GT two intake and two exhaust the air flow is very good. The ability to slightly adjust the direction of the air flow from the side intake fan helps to eliminate pockets of air that often form inside a larger case like the Level 10 GT. Still we do wish there was at least on fan pulling in cool air from under the L10 GT if not two (one in the main part of the case and one under the drive stack. This would have improved cooling quite a bit we think.  Let’s not forget that you can also adjust the speed of the fans to increase the amount of air moving through your Level 10 GT so even though there are only three fans you can still move quite a bit of air.

Aesthetics -
Aesthetics is a rough subject; what I think looks good might be unattractive to others. Because of this I usually do not subject you to just my opinion of how good or bad a case looks. I tend to ask a wide array of people and get their input. This should give you a much more broad impression on why people might find this case good looking or not. We use out standard 1-5 (one being terrible and five being awesome) we ask two questions. On a scale of one to five rate the Level 10 GT for coolness and then we ask the same question for overall looks. Then we ask for a one or two word statement that best describes the Level 10 GT for them. I was able to ask a few people about it while I was photographing it in Bahia Honda Key the results were interesting considering the demographic.
For me the Level 10 GT is a bit awkward when you look at it from the front. It just does not look right. Now when you turn it sideways all of that changes. The side view looks very clean and has an almost artistic look to it. It is not as clean as the original Level 10, but there is something about it that grows on you. Another item that I am not overly found of is the large amount of plastic used in the Level 10 GT. I know this was to save on costs, but it also gives a slightly cheap look to the drive bays. They really do look like they do not fit properly when you look closely.

Now, all that aside I have to say that the combined whole (when looked at from the side) is just plain cool. The large colored fan that extends out in its own housing and the rectangular window that gives you a peak into the inner workings just makes for a nice visual (as the LEDs from the fans light up the interior). The white color also adds to this effect especially with the actual door being black colored.   I have to say that while I like the look of the Level 10 GT Snow Edition, I still think it is a pale comparison to the original Level 10 case.
