4/ 5

Pros: - Enormously spacious
- Highly modular allowing a for diverse builds
- Good aesthetics
- Good airflow
- Easily removable air filters from the top, front, and bottom

Cons: - Heavier than my Cooler Master ATCS 840 case which this replaced
- Plastic on exterior, especially on a halo product of this price, diminishes aesthetic value
- IKEA assembly-like instructions
- No shroud over fan control hub on side
- Built-in cable management started out good from front panel, but looks like they gave up halfway through
- Came w/ stock fans. I'd prefer good fans with a higher price or no fans at all with a cheaper price

Other Thoughts: - Lots and lots of screws.
- Requires planning before assembling or you'll be spending the whole day building.
- I wish it had small wheels that could be removed so it's easier to move around

Great case! - Cosmos C700M

Pros: MANY screws. This is a blessing and a curse. The case is massively configurable, but I am using it in its standard configuration. Yet still, many screws.
It has a controller for its four fans included fans, and has expansion room for two more.
I used three of the four 3.5 drive trays. Good design, many placement options. Special screws are included for mounting drives into these trays.
Really nice cable routing capability, with lots of tie-down attachment points. My first really tidy build was the result.
This is a very heavy case.
Many screws.This is nice in that everything can be moved around to better suit your build.
I opted to remove the front dust filter and use the filter built into the front cover. Two filters in series is too restrictive.
I used the remote video card mount (which is very solid and well-built) with the included riser cable, and tilted the card back at an angle, roughly 35 degrees. This is nice because you can SEE your expensive rgb video card, AND it gets it away from the glass for better cooling, but doesn't cut into the motherboards airflow path. Multiple wins.
Fit is near perfect. The case back (side opposite glass) closed easily due to the excellent cable routing features. No cramming.
The front panel supports four USB 3.1 connectors and one USB 3.1 C connector. So I was able to use my X470 Taichi's two available 3.1 headers and the available 3.1 C header.
The rgb effects are excellent.
I love the really solid metal skids at top and bottom.
Did I mention MANY screws? And heavy?
The net is this is a beautiful case that allows anyone to effect a very clean build.

Cons: Many screws. This is a burden but one that has to come with the reconfigurability aspect of the case.
This is a very heavy case that only gets heavier when built.
The remote video card mount PCIe cable attachment method could use a little engineering time. It works, though.
The manual is terrible. Really needs work.
I would have liked better quality fans. The fans appear to have non-standard cable extensions, but the fan controller seems to have "standard" connectors. The manual is no help here.
A couple more fans would have been nice.
The integrated controller has connectors that are unused, with no indication as to their function. The manual is no help here.
The case costs a lot. You get a lot, but this is not a value proposition case.

Other Thoughts: First, this review is for the Cooler Master C700M, not for any of the earlier versions. Many of the reviews I read here are not for this case. This is important, because the other reviews cannot inform you of the features of this case.
I just built this yesterday, 28 Nov 2018, so if things change I will update this review.

Premium Case

Pros: First, if you are looking to buy this case, understand that it is a Premium Case and as such this review is based off of that premise, I will not bash the case because of "price" and "there are cheaper cases that have better airflow and its sad that people wont understand why their cpu is burning", hate this kind of bashing for products in general that stem from the price tag of an item that the manufacture clearly stated that its their premium package.
- The case is bigger than big, saw multiple review videos, new it was big, its bigger in person which is great because you can really customize it however you want including adding a custom water loop, its awesome.
- Its beautiful, which I know is subjective, but all of my friends have described the case as beautiful, the curved tempered glass adds a lot to the looks of the case which some may think that its just to make it look fancy but it genuinely catches the eye and it also feels nice when opening the case.
- The case is heavy and the metal gives it a great feel, it doesn't feel cheap at all which is a great thing when your buying a premium item, no one wants something in this area that feels like its made of cheap plastic or like it cant even hold its own weight.
- Lighting is great and looping it with the rest of the lighting that you add yourself (fans, gpu, whatever else) makes it stand out even more than it already does, again, the only limit you have with this case is your imagination.
- Cable management with this case is a breeze, the straps in the back make the cables look nice and its easy to hide everything.
- Riser Cable plus bracket that comes with the case so that you can show case your gpu is fantastic.
- Airflow isn't an issue and you can direct fan air in whichever direction you want really since you can position your motherboard and gpu in any direction you want and plus, you have more than enough space to have a custom water loop which is what I'm going to do next.
- There is so much more to say because of how drastically you can mod this case but I suppose these are my favorite points that come to mind.

Cons: Nothing really, case came without a single scratch or dent.

Other Thoughts: If your looking to build a show case pc or just really want a premium case that will stick out, this case will do that, don't listen to the haters who cry that its too expensive and say it should bring other things because of the price point, ect. life is too short and if your looking to buy this case, price should not be a concern cause its kind of a case that you want to go all out on, not a case where your looking to save money by using the stock cpu cooler that came in the box...

Beautiful Case

Pros: Like I said, beautiful case. Very roomy. Love the external LED's.

Cons: I don't own this case yet. Maybe the price.

Other Thoughts: I watched a video on Jayztwocents. He built a beautiful rig in this case. Wanting to purchase this case.

Best case that ever lived!

Pros: HUGE case, the pictures do not give you any sense of how big it really is.
Cable Management features are awesome, if you can't get it right it's going to be hidden anyway.
RGB Lights are awesome too if that's your thing.
LOTS OF Room to build in.
It comes with a GPU riser cable and mount which makes it even more worth it.

Cons: Nothing that would require knocking off an egg in my option:

The fan hub requires a molex power connection whereas the extra RGB cable for adding more lights requires Sata, might of been due to being rushed or just CM not sure what type of solution they want to go with yet.

The 3 front fans do not have RGB nor does the exhaust fan , with the price point of this case you'd think they would install RGB capable intake fans but most enthusiasts like me will replace them anyway.

Other Thoughts: It's heavy, in the box its about 60 pounds and very bulky but this is to be expected. Don't hurt yourself trying to carry it up the stairs. I am pretty sure the fedex guy has me on his list of people to dislike.

Motherboard: ASUS Maximus X Code.
