This case is hands down one of the best cases I've ever seen and its really close to perfect. Here's why:

The good stuff first:

1. Huge case. If you were looking for a case that holds almost everything you want, Congrats, you just found it. OK there are other cases out there that hold plenty of stuff like the Mountain mods cases but they dont come with all the fans or accessories by default you have to buy them separately.
Here is what this case has in it: room for:
a. 10x 120mm fans
b. 13 drive bays.
c room for a full liquid cooling kit.
d. room for extended power supply.
e. m-atx ATX E-ATX XL-ATX SSI CEB and SSI EEB motherboard form factors.
f. 11 expansion slots
g it can fit a 140mm fan in the rear
h. 1x 200mm on top.
i. 2x 120mm fans on the side (optional)
j. can fit 2x 140 mm on top. (optional)
k. 4 channel fan speed control.

2. The case is made of steel. (not all of it though)
3. the bars (or handles) are very sturdy
4. the front door merely needs a touch and it slides down automatically.
5. side panels come off easily.
6. the case is easy to clean because you can remove the dust covers easily.
7. looks stylish.

Now for the negatives:

1. the case has a lot of plastic in it. I would prefer more of the case to be aluminum or steel like the top fan grill as well as the retention clips that hold you're 5.25" devices in place.
2. No side window as of this writing but the side panel has noise dampening material in it.
3. This case weighs in at no less than 47.3 lbs. Imagine how heavy it will be with all your hardware. For me this isn't much of an issue because I don't move my PC much.
4.

First off ... this case is huge and heavy ... and huge. Tons of room for a boatload of hard drives. Wires dont run inside the main compartment of the case which clutters the innards. Instead they run out through the back of the motherboard area through slots on the side of the case which massively minimise clutter inside. First of all just looking at it is beautiful, it is a well thought of and designed case. From the nice sliding mechanism for the front panel to move up and down for showing of the CD/DVD drive in front to the sliding panel on top which covers and protect the power and fan control panels in-front of the system from wandering hands.

Both door panels easily swing open from rear to front, and have the ability to just lift off hinges to help work easier.

The design of the chasis allows for maximum air flow to kelp keep your system running cool. Inside the case is divided into two main parts, the upper part with the motherboard etc, has its on air circulation. Aswell as the lower half of the case where the power supply is and optional hard drive are have their own air circulation.

The power supply at the bottom with its own sectioned off compartment allows for the thick cables to be managed easily down there and only snake up the what you need for where.

Wires are all managed behind the motherboard, which is on the outside of the frame, towards inside the right door (if you have the front of the case facing you.) Inside my case looks neat, clean and sexy, but open the side door where the back of the motherboard is and its a disaster ... looks like an AT&T switchboard. But it is well hidden with the design of the case.

At any given moment, my system runs at a nice 30-40 Celsius.

My specs are below ...

Me: I love this case. It's beautiful. It's elegant. It's imposing in size. It will hold everything I plan to put in it. I loved the case when I saw it used for the Dream Machine 2011. It has been well received by reviewers and builders alike. Does it do everything for everyone? No. So who should buy this case?

This is a 5 star case if:

1. You already think the case is beautiful as is. As in, you aren't immediately thinking man this case would be perfect with a window (cause at this point it doesn't seem like it is going to get a factory built option for 1). The construction of the doors apparently makes the process for a window very difficult. I have seen some beautiful mods of this case, everything from painting to windows, to one that looks like the eagle gargoyles in NY. So it's possible. But it isn't easy and I dont think they made it with modding in mind. It's a super car, not a hot rod...people don't normally mod their super cars. I hope that analogy makes sense. If you're looking for a hot rod base to build your dream case, this is probably a three star case.

2. You plan on using air or a mixture of air and liquid cooling or a moderately heavy amount of liquid cooling. I say this because a lot of the complaints seem to center on the inability to put the largest radiators in any configuration natively. They designed the case to have a lot of room and a lot of air flow so you will be able to push your CPU and GPU's fairly hard without the need to liquid cool everything. If you're a bench marker who wants to be able to put a 4 80 in push pull in the top and 3 60 in the bottom push pull and..and...it may take a little creativity and moderate modding.
