First off, let's make one thing clear: The In Win 904 is not a gamer's chassis. It is for those who want a beautiful-looking system first and foremost. Sure, you can install fully sized components into the chassis, but its unique design limits it somewhat in terms of cooling choices.
So, now that we got that out of the way: The In Win 904 once again shows the company's commitment to thinking outside of the box by combining different materials to create beautiful cases. These naturally come at a price, but why the chassis costs 180 euros including taxes in Europe and 280 US dollars in the States without the government’s cut is a mystery to me.
In Win tried to make a case that utilizes glass. One that is not quite as out-of-this-world as the D-Frame, it can still hold its own in a living room or a hotel's reception area while blending right in, which it does so extremely well. You can, on top of that, fill the chassis with normal, fully sized components, like a PSU, mainboard, or graphics card, but will have to watch the size of your CPU cooler; that is, unless you don't mind using a radiator in the back. While the option for such a choice is nice, it would interrupt the look of the chassis too much to be truly viable to its target audience.
I won't delve into the interior too much, but some of its highlights are the hot-swappable bays and the optical drive's unique placement. It would have been nice of In Win to include a 140 mm and 92 mm fan out of the box to give the chassis a bit more value for its price tag, though. Overall, In Win has shown that they have the guts to gun for designer glory once again, and for that, they should be applauded. The In Win 904 may be expensive, and it may not offer all the functionality other cases in its price segment sport, and, heck, it is not nearly as amazing as other cases in terms of overall compatibility, but, oh boy, does it look good, and that is exactly what will matter so much more to the crowd the In Win 904 is for.
