1. Remove the bottom plate

There are 15 screws keeping the bottom panel in place. 14 of them have Torx heads, and the one in the bottom right corner has a Phillips one. Also, it stays attached and lifts the panel, so that you can start the prying process from there, although the panel itself lifts up pretty easily.

2. Battery

Thankfully, this notebook is fitted with a beefy 90Wh battery pack.

3. Memory and storage

As you can see, there is only one RAM SODIMM slot here. This is because there are 16GB already soldered to the motherboard. According to ASUS, the maximum amount you can fit is 32GB for a total of 48GB of memory. As for the storage, you get two M.2 PCIe x4 drive slots, which support RAID 0.

4. Cooling system

Here, we have a pretty sophisticated cooling solution. It employs a total of five heat pipes. Two of them are shared between the CPU and the GPU. Then, you get one more for each of them, as well as one heat pipe cooling the VRMs and the graphics memory. They end up at four heat spreaders, two of which are quite massive. After that, the fans, which draw most of their cool air from behind the second display, push the air outside of the chassis. By the way, ASUS is once again using a liquid metal thermal compound for the CPU.

Well, it is not exactly new, as it is more like a refresh to last year's device, but the ROG Zephyrus Duo 15 SE (GX551) does not only have a mouthful of a name. It seems like ASUS has ditched Intel for AMD's brand new Zen 3 processor architecture, and you can max out the notebook with up to the Ryzen 9 5900HX. Needless to say, you also get to choose from some Ampere graphics cards. Thankfully all of them (the RTX 3[...]
