It was easily removed by removing the screws and lifting the case up. Four 3.5-inch drives can be installed in the central inner case. The front has two internal cases that can accommodate 5.25-inch drives on both sides, and one internal case that can accommodate 3.5-inch drives in the center.

After that, it is OK if the screw holes are aligned and fixed. The button of GM500-G could be attached to the outside by sliding the cord into the gap of the case. You can also fix a 5cm fan on the front side of the central inner case. Since the RM41-506 does not have a fan attached to the front, it seems good to install a fan in the center inner case considering the airflow. No responsibility is taken for the correctness of this information. The listed offers do not constitute legally binding advertising claims of the merchants. The dimensions of the RM41-506 are 430 mm in width, 176 mm in height, and 446 mm in depth, and it looks like this when comparing the size with a notebook PC with a width of 283.5 mm × depth of 203.8 mm. Due to the large number of LEDs on the front panel, connecting the panel pins is a bit complicated. Please note that the pin layout depends on the motherboard.This 4U chassis makes for a nice short-depth NAS if you're trying to keep things quiet. The tolerances on the drive bays aren't too great, so you'll have to force some parts into place when reassembling. The contents are RM41-506 main body, fan extension cable, various fixing tools, instruction manual. In addition, the RM41-506 can also install a 'GM series' power supply made by SilverStone that cannot be installed with a normal ATX power supply compatible case. This time I will attach 'GM500-G'.

You can remove the inner case on both sides by removing all the fixing screws. You can install three 5.25-inch drives in this case. On the front side, in addition to the power button, reset button, and two USB ports, there are LEDs that indicate power, disk access, and LAN port link up.
