Let me start my closing arguments with the dislikes and get them out of the way. First of all, seriously, how do you forget about the need for screws to mount a power supply? In a $40 case I might let that slide, but for this amount of money, I can't just let that go. On a personal level, I am not a fan of what is left when the bay covers are removed. The sleek elegance of the front panel to me is destroyed once you break up what is otherwise continuous brushed aluminum. There are also some out of square and solidity issues I noticed. Along with the fact that I had to force the back of the chassis inward to mount my video card, when the door panels are off, this case will flex a fair bit. Nothing that will be detrimental in any way, but I have seen more solid cases from Corsair in the past.
On the plus side of things, the 750D has a lot going for it. It was one of the easiest and quickest builds I have put together, and even so, I still ended up with a clean and well managed setup. I like that they supply fans to go with this chassis that were capable of keeping my components at average temperatures, they also did it in near silence at 32dB of noise at a foot away from the chassis. I like the overall styling and I especially liked the internal modularity. While I opted for air cooling and am pleased with my results, for the water coolers out there, there is room for up to four radiators, and even options to move from 120mm radiators into 140mm solutions.
I think the SSD racks, while new and sort of fancy, make a great use of typical dead space in the case, and with the HDD racks out you can put the SSDs proudly on display through the large window and see it next to the rest of the kit you installed. In the end, I do like the Obsidian 750D and what it offers, there just are a few things to consider as I mentioned above, and with more knowledge, if you do plan to buy this chassis, you are better prepared for what you are getting.
Since I know after reading this Corsair will jump on adding more screws for the PSU mounting, I really can't hold that against them too harshly, and with the rest of the "issues" being based on personal tastes or certain phases of the build, which will likely only show up once for most buyers, I am left with a well priced chassis at $159.99 that I still think is worthy of that pricing. Corsair really does step up and make installation of the system very easy, and with the helper riser on the tray, you could even install the motherboard with the case in the upright position without much hassle. While the points are going to reflect the chassis as I received it, I really do like this chassis, and for those that like the sleekness of the Obsidian line, but done need the enormity of the 800D or 900D, this is definitely the way to go.
