Assembly
Installing the motherboard within the H-Frame is done by traditional means. Simply place the spacers on the thick, blue aluminum sheet and the board on top of those. There is enough space for the top-blow Phanteks fan, but a full-tower variant will not end up with enough space. You will have to make sure to find one that is compact enough.
Installing the hard drives into the trays requires the use of some screws, but that is easily done by securing the drives onto the contraptions outside of the chassis. The 2.5" tray is a simple plate with four holes, but it works, as you can see, flawlessly.
Prepping the 3.5" drives requires one more step, as In Win ships them with 2.5" trays. You will have to remove these to clear up room for traditional, larger drives. A 3.5" variant is then secured using provided screws.
Once in place, simply slide the tray back into the bay of your choice. Last, but not least, push down on both spring-loaded thumbscrews and tighten them down. This way, the bay won't budge, and you will not have to worry about vibrations through the area.
Installing the optical-drive bay bears a small surprise. When empty, the frame's back not only acts as something to fill the bay, but also as a cover for the front, which is why there is an In Win logo on that side of the bay. But filling and installing the bay also means turning the bay around, making its open front face outward with the back in the rear. While this is pretty cool, it makes the SATA connectors a bit hard to reach, as you will have to feel your way around this area of the case.
Installing the power supply is done by traditional means. Just make sure you use the foam spacers to eliminate any vibrations being transmitted from the PSU to the chassis frame.
With everything installed and in place, the H-Frame makes a bit of an untidy impression. Using the included zip ties will minimize this issue, but this is an open-air chassis, and you do expect to see cables somewhere. Thanks to the firmly attached SATA data cables, you at least avoid a colorful mess in this area.
Finished Looks
With everything in place, the In Win H-Frame is such an unusually cool sight that you may forget having spent a lot of money on design instead of functionality. You can clearly see the internals of your system from the front or the rear of the chassis, and that mess of cables does not even look out of place anymore.
A small blue LED lights up after turning on the chassis, and the ODD opens up at an angle like a boss. You can also clearly see the parts within the chassis from the top.
