A look Inside

Taking the ASRock 4X4 BOX-4800U apart is very quick and easy. First, remove the four screws on the bottom, which will allow you lift the bottom plate off and install your system memory, M.2 SSD, and SATA HDD/SSD, and so on.


The internal layout is straightforward enough, and while further disassembly is not necessary for most, it's still useful to know how it is done. You will want to pay attention here if you need to deep clean the heatsink and fan down the road to improve temperatures. Before the motherboard can be removed, remove the front fascia. A couple of plastic clips hold it in place, and it should come out rather easily. With that out of the way, it's time to remove the screws securing the motherboard to the chassis.


Next, remove the screw holding the M.2 bracket in place so it can be lifted out. This will remove any tension on the WiFi antenna wires, meaning you can remove the screw holding it in place as well. With the Intel WiFi 6 AX200NGW card removed, you can simply set it aside. At this point, the motherboard can be removed from the chassis.


Looking at the bare motherboard, the bottom of the board is where the two DDR4 SODIMM slots are located. At the top, you have your M.2 slot for either SATA or NVMe SSDs and a second slot for the WiFi add-on card. Meanwhile, the heatsink and fan are a bit beefier than I expected. The heatsink, while small, does make use of two heatpipes, and the fan used to cool it is from Delta Electronics and has model number BSC0805HA-00. Just be careful if you remove the fan for cleaning as the CMOS battery is attached to its underside.
