In Win already turned heads with the H-Frame. They are clearly continuing the trend by creating one crazy case after another. The D-Frame takes things to new heights with its manufacturing process and design elements. As the only case I know of that uses die cast metal for a core and properly welded bars as an exterior shell, the D-Frame is pretty incredible. Such design naturally comes at a price. A case clocking in at 400 USD is certainly not something to take lightly, but that is, in the end, the price of being extraordinary. You also have to pay magnitudes more if you want a table made of an old jet turbine instead of a normal glass table. The same principle holds true for the D-Frame, yet it is still functional enough for everyday use, which means that you can build the rig of your choice with this chassis. All the drawbacks of the chassis can be attributed to its design, so there isn't a whole lot else left to say.
In Win has outdone itself again with the D-Frame as a chassis constructed around an ultimate design idea. Be on the lookout for this case if you want one—In Win has mentioned that only 1000 pieces will ever be sold.
