Cooler Master Cosmos SE Midnight Black Mid Tower Extreme Performance Case with Side Window w/o PSU is rated 4.8 out of 5 by 5.
Rated 4 out of 5 by from Great case for a custom build I have always custom built (for the enjoyment as much as value) and this is one of the better cases I have used. It is very large which brings benefits to cooling and gives you complete choice over GFX cards (even the very large Titans). The only downside I could find was that the top cooling section was difficult to use with a Kraken x41. I wanted to put the radiator in the top with the fan below (i.e. push config) but there wasn't enough space for the radiator itself (due to oddly placed case brackets) and there is no room for the pipe to get back to the motherboard anyway. There are plenty of other options (back, front, top in pull config) but given the flexibility of the rest of the case, this was a slight disappointment and would limit options if using a larger radiator such as the X61 or the H1000i

Rated 5 out of 5 by from Excellent case and quite big Even though it states that this case I meant to be the little brother of the cosmos II, this is a massive case and really well built. There is plenty of space for hard drives and cable management is incredible. The fans provided with the case with blue LEDs compliment the blue lights in the front. Overall happy I got this rather than spending double on the cosmos 2

Rated 5 out of 5 by from Great case Very good case. Only issue for me was the holes in the motherboard panel could be largest to accommodate flat power cables. Apart from that a great case.

Rated 5 out of 5 by from New X-99 Build This is a fantastic case, extremely strong build quality, and very quiet with the right fan set up. I have used an icy dock 4 x SSD bay that slots into one of the two 5.25 bays, and have installed a back up HardDrive in the other 5.25 bay. Installing Windows via USB is a doddle and have no other use for a dvd drive, but thats my preference. This enabled me to remove all hard drive cages improving airflow, and also allowing me to install my H100iGTX in push and pull using the provided brackets that come with this case. This has to be installed at the front of the case in place of the hard drive wont fit in push n pull at the top, but will fit fine in push OR pull if you prefer to keep the hard drive cages in.

Rated 5 out of 5 by from its Good Great Case, hard drive bays are abit stupid as they went with more hard drives is better and with less cooling?

Questions & Answers

H100, top or front.

Where can the H100 be installed?
Asked by: Random
I would suggest you are probably looking at either front (after removing the two large blue fans that come with the case) or top, yes. The top section probably wont fit the H100 radiator (and there is no space to take the pipes back to the motherboard anyway) so you are limited to putting the radiator on the motherboard side of the top shelf, then using the fans in the top section in pull config. You may be able to push from the motherboard side, but my Kraken X41 was getting in the way of the CPU power and other mounts on my Maximus VIII when I tried that. As your question suggests, it certainly wont go on the back. Hope that helps
