The Assembly Process - The Insides
The next step, with the exterior done, is to fill up the insides by adding all the necessary bays and the functionality. This is done by using the black screws to attach parts to the die cast centerpiece. Its arbitrary shape actually serves a very specific purpose. Every intersection and all the straights have various mounting points. I placed the motherboard expansion slot frame first by using two of the black screws.
Next is the hard drive cage that can hold up to three drives. It also comes with a plastic sliding lock to ensure that an inserted drive does not fall out, since the case may be flipped upside down. In Win usually numbers each of its D-Frame cases individually as only a limited number of them will be produced, but the one we got was simply a "Review Sample".
At this point, the case still lacks an external drive bay. In Win has taken the same tray shape as that of the H-Frame before editing it slightly to fit onto the D-Frame. The bracket with the power button, LED, and I/O is placed above the external drive bay. You will have access to a pair of USB 3.0 ports and the usual audio connectors.
Although this case is completely open, In Win has included a total of four frames for fans. Three of them are to be installed at the floor of the case, while one can be placed right behind the D-Frame's front.
With all the internal parts in place, the only thing left to do is to slide the tempered glass side panels unto the case—using the big black nuts to hold them in place. The task of assembly might seem daunting at first, but it is no harder than building something out of LEGO or putting together a piece of IKEA furniture.
