This is a guid that shows you a way how you can change the fans in your supermicro CSE8?6 case. There are multiple versions of 80 * 80 fan cases available some are easier to use for this modification than others. In the next secion I will introduce two fan case variation.
In the picture above you can see that the FAN-0126L4 case has a notch that makes it harder to drop in standard (less thick e.g. 25 mm) fans. The FAN-0094L4, 672042020317 case on the right does not have this notch and can be easily used for this mod.
