A Closer Look - Inside

To gain access to the interior, simply remove the fourthumb screws holding each glass panel, pulling the panel off the now exposed aluminum pins. You will notice the eight motherboard expansion slots in the top right away. These utilize the fold on top in an ingenious way and each come with an individual screw hole, which has been drilled into the aluminum sheet directly. Even though it looks as though In Win does so after anodizing the case, the company even goes as far as anodizing the chassis after cutting all openings out and drilling all holes, which means the black and red version comes with screw holes that are anodized red – yes, pretty crazy. On the opposite side of these holes are eight neatly cut out openings to sink your expansion cards into. These are, again, part of the aluminum sheet.


Turning the case on its other side, you will notice the four 3.5/2.5" hard drive trays. Each individual unit is made of the same massive 4 mm thick aluminum material and comes in exactly the same anodized color. There is also an opening along the bottom half of the motherboard area. It is used to route cables from the outside into the interior, although it also adds a nice little design element.

You may notice that there is no opening for the motherboard's CPU area. While this would have reduced weight overall and made assembly easier, it would have also disturbed the S-Frame's overall look once fully assembled. In Win explicitly decided against doing so for the sake of the best possible design.


Looking at the hard-drive trays, they rest on a fold and extrude into the chassis, which will make every drive you install a clearly visible PC component once your system has been assembled fully. Below these are various mounting holes. These are for water-cooling gear, like a pump or reservoir.


A T-shaped opening in the rear is used to route PSU cables from the outside into the interior of the chassis. It is quite large, maybe even a bit too big to some users. Above that is a plaque which not only holds the brand and the case name, but the chassis' limited edition number. As this is our special review sample, In Win placed our TechPowerUp logo there instead. Interestingly enough, there is an opening right behind the plaque. It is usually hidden by the PSU bracket on the other side, so it serves no real purpose. Upon closer inspection, a similar hole was found in the front, between the HDD trays and the I/O element. It seems as though it is required in a manufacturing step, and In Win goes to some lengths to hide it in their finished product.


Even though the S-Frame is clearly a designer chassis, it is also the first of its kind to allow for a large radiator to be installed. While the H-Frame did allow for individual fans to be placed within its belly, the S-Frame comes with a bracket intended for radiators as large as 360 mm. This piece can easily be detached for easy assembly and is made of the exact same material – 4 mm thick Aluminium.


Last, but not least, all the cable within the S-Frame come sleeved in black and feature black connectors. This is to ensure that the overall design is not disturbed once the PC has been fully assembled. That said, you had better use a PSU with black cables to keep with the theme.
