I ran into a couple hiccups along the way, but in whole the build is very satisfying. I haven't tweaked the OC settings on any of my components (still a little new to the PC world), though I imagine that is something I will eventually stumble into. The hiccups mainly involved the H100i, they tell you that the mounts have been adjusted for the Haswell sockets (1150), but really its just an extended oval mount, making it sort of a jigsaw to mount on the back of your motherboard. Once you are actually able to align the brackets into the motherboard and screw on your front mounts, you'll notice (on a Micro-board at least) that the mounts are intended for a much thicker board. I'm not sure if this was because of the specific dimensions of the GRYPHON or to what nature, but I ended up applying my own rubber washers (same kind used to silence your fans) to the back of the board in order to secure the pumps' mount. I thought about boxing the whole thing up and sending it back, but realized that Corsair probably would have gave me similar instructions. I will also note that the stock fans that come with the radiator are efficient, but terribly loud. It really doesn't bother me because I think it sounds pretty beastly, especially when I can control their speed through the Corsair Link 2 in the desktop. However, if your looking for a quiet operation, then I would suggest upgrading. The other hiccup I came across was my drive occasionally cuts out, more than likely because it was the cheapest and highest rated drive on the site. Though it has served its purpose and has worked, eventually, for all of my drivers. Another bust I had was in my keyboard, apparently the unify devise is a hit or miss, meaning some of them work and some of them are a little more sketchy. If you get a bad chip, the connection between the chip and your USB mount won't be flush, resulting in a loss of connection. However, you can simply send it back and get a new one. In respects to performance, like mentioned earlier, I'm highly pleased. I enjoyed the build process and I'm enjoying learning the depth of these computers. I would say that right now I average BF3 at about 80 fps on ultra and it runs fairly cool. A truly shocking difference for me, considering I've always played on a console prior.
