One of the best cases ever made. I have built many PC's and this thing is a builders dream. I have other fractal cases but this is the best.I bought this to house my home server build and really wish i had discovered it a few builds ago. It is sooooo quite. You only know its on because of the power button. No temp issues. Massive amount of room for drives. Absolutely love it.

Let's get one thing out of the way. This is not your rgb flashing strobe light case, this is not made to satisfy hardcore gamer aesthetic. However, it is silent, understated, and has every feature many modern cases are missing. That is, a full set of drive racks, optical drive bay, and silent fans, cable management, noise dampening... If you are the target client for this I think you already know

A very nice, well made case. One of the few that provides for 5.25" drives like optical drives. The case is a little wider than most but that makes it very roomy to work in. It comes with two preinstalled fans and has locations for 6 more or 4 different water cooling options. it has drive bays for up to 7 drives in addition to the two 5.25" bays. It has a reasonably well written user guide and lots of screws and hardware for the various components like hard drives.
