A look Inside

Taking the ASRock 4X4 BOX-7735U/D5 apart is a relatively painless process at first glance. Much like its siblings, you will need to remove the four screws on the bottom, which will allow you to lift the bottom plate off, giving you the ability to install system memory, M.2 SSD, SATA HDD/SSD, and so on.


Before digging deeper, you will find the MediaTek RZ616 Wi-Fi module pre-installed and ready to go, you will need to remove it if you plan to do a complete disassembly but more on that in a moment. First, you will need to remove the rear I/O shield which needs to be un-clipped and then pulled out. Then remove the Wi-Fi module and carefully move the Antenna wire from under the M.2 SSD bracket (black plastic).


Now remove the RZ616 Wi-Fi module and carefully move the wire around the black plastic M.2 SSD bracket. Now you need to remove the two screws near the rear I/O that hold the motherboard to the chassis, at which point the entire system can be removed.


With the system pulled out, you now have access to the CPU cooler and fan, with the fan model number: BSC0805HD-00, which is made by Delta Electronics. There is also a plug on the side for the CMOS battery. Beyond that, you have a copper cooler with a small copper radiator which should be sufficient for the Ryzen 7 7735U's 28 W TDP. However, the unit also has a performance mode that boosts the TDP higher, which makes me wonder if the cooler can handle that much heat.


Finally, before I put everything back together, I installed the memory and SSD, a quick and painless process. For M.2 2280 SSDs, you use the provided screw to secure the SSD to the standoff once firmly inserted into the M.2 slot. The memory is much the same; slot it in fully and then push it down. Now, all that remains is to install Windows via USB key, which is incredibly simple thanks to the Windows Media Creation Tool, as you can download the tool, set up a USB drive, and have Windows installed in less than an hour if your internet speeds are decent.
