InWin 103



The following system was used to test the fans:
– Processor: Intel i5 9900K @ 5GHz
– Motherboard: ASRock Z390 Steel Legend
– Memory: Crucial Ballistix Tactical Tracer 16GB @ 3000Mhz
– GPU: ASRock RX 590 Phantom Gaming U
– SSD: Crucial MX 500GB
– HDD: WD 1TB Blue
– PSU: In Win 750W Gold
– CPU Cooler: Silentium PC 240
– OS: Windows 10 64-Bit (After April Update)

Starting with the rubber grommets, there are none to be found and that’s not the worst thing, the spaces for routing the cables to the motherboard are too far for a good cable management to be had.

There is also no space for the CPU cable to be routed cleanly to the motherboard connector, in this case, you are forced to route the cable in front of the power supply fan, adding more noise into the system. At the bottom of the motherboard there is enough space for small cutouts that would have allowed for the USB and audio cables to pass through, unfortunately, there are none to be found, this makes routing the cables from the front of the case, a hassle, increasing at the same time the the fan installation difficulty.



The interior of the In Win 103 is close in design and structure with the interior of most cases from the 100 and 300 series from In Win. The power supply is mounted at the top and the air intake is at the bottom of the case, through a dust filter.


The storage options four in total, you can install up to two, 3.5” drives into the plastic cages that are removable and will slide forwards. These cages while plastic, do have some rubber washers to dampen some of the vibration created by the storage units.


The rest of the storage mounting spots are located on the back of the motherboard tray, in the shape of two SSD metal trays, these are held in place by a single thumb screw each.


Final thoughts

The In Win 103 can be acquired for approximately 80 US Dollars or Euros and at this price point, there aren’t that many cases available with this level of build quality and features.
This is not a bad case; it is quite good in fact. The build quality is great, and there is plenty of space inside for any graphics card or motherboard, as well as having the possibility of installing a full water-cooling loop.

The thermal performance is up to what fans you decide to install into the case, as In Win decided to include none with the 103 model. This can be seen as a good thing as many users decide to replace the factory included fans with their own preferred models.

In conclusion, the In Win 103 is a mid-tower case that offers great build quality and a different approach to the internal space layout, with the power supply mounted at the top and the intake being at the bottom of the case. There is also an addressable RGB system integrated into the case, In Win including a controller for it as well as the required connectors.
