Hi,
May I introduce my new ITX system, this time I'm testing the Sliger SM560. I will still make one or the other modification, e.g. a more flexible end of the internal USB3.0 cable, since the internal Sliger cable is currently obscuring the view of the beautiful RGB RAM from the outside. A new graphics card will be coming soon, there is enough space now. Possibly it will be "only 2 an RTX 3050.
The assembly was done quite quickly - I'm a fairly experienced PC hobbyist, among other things with the even smaller DAN A4-SFX. However, the supplied instructions from Sliger and Density are partly unusable and incorrect, e.g. the assignment of the screws is not correct in my opinion. The instructions were right, however, that the installation of the internal power cable or its socket must be done AFTER the graphics card has been installed. Unfortunately, I always have to unscrew the cable when removing the card - that wasn't the case even with the DAN.
The airflow is very good, the Noctua Fan-Duct (NA-FD1) for the NH-L9a cooler actually contributes a lot, i.e. actually around 5° Celsius cooler! The optics are also excellent, and the case also has a good touch quality. It's a pretty heavy, small chunk...!
