I built this computer mainly for gaming and some school work (lol). I wanted to try out the new NZXT Noctis case as it looked pretty cool and it had the same well rated interior as the H440.
Overall, everything did fit nicely except I couldn't fit the kraken with the tubes going towards the back of the case because they were too long and would get stuck in the rear fan. I therefore had to take out all the hard drive cages to leave room up front for the tubes.
The intel i5 6600k is now overclocked at 4.43Ghz and idles at around 30-35C.
Since i changed the base clock to something around 102Mhz, the RAM, along with the XMP profile 2 ended up being clocked at around 2900Mhz instead of the original 2133.
As for the GPU, the R9 390 came up last minute as it fit perfectly in my budget and offered good performance for the money. It is overclocked to 1125Mhz and idles at 65C and reaches 85+ under load. I am probably going to upgrade to a full water cooling custom loop since this is pretty damn hot
Another great thing about the case is that it has a fan hub to connect all the fans together. Using the kraken's cpu header for all the case fans, I was able to control all the fans using the CAM software instead of going with an additional fan controller.
I also hacked some cheap rgb led strips with switches for each color, running on a molex as I couldn't use the original remote that came with them (have it in the car) Shoved all that stuff in the psu shroud to hide the wires.
There is also an added serial port connector at the bottom of the pci slots since it was needed for some hardware. It looks terrible but it does the job.
Gaming is just great, 1080p, 144hz, FreeSync, it runs pretty much most current games such as Black Ops 3 maxed out at 100+ fps. GTA V being an exception runing at merely 40fps lol
