Removing the thick, glass side panels we can now clearly see the internal layout and design of 904. The motherboard tray and even the cable braiding is been given a sleek black colour-scheme and while some of 904 retains characteristics to the common computer chassis there are also some subtle alterations – such as HDD cages and cooling fan placement.

There are actually no cooling fans pre-installed and only two locations for attaching such a device. IN WIN has made allocation for a 90mm rear exhaust and a 140mm intake above the FP connectivity. Stock cooling performance is certainly going to have a weakness but even adding in fans may not yield promising results either.





Beginning at the bottom of 904, we see there is a platform for placing the PSU. This platform sits above the 5.25” drive bay and unfortunately has no anti-vibration padding or the option for a dust filter – in fact, IN WIN has included a small sticker to instruct installers to mount the PSU with the fan facing the inside of the chassis.



Moving our way up through the case we see there are a total of eight PCI expansion slot covers, there are no ventilation cut-outs on these covers and just a standard screw is used to secure them so you will need to get out that trusty screwdriver to add/remove.
