1. Remove the bottom plate

11 Phillips-head screws are holding the bottom panel in place. After you undo them, you have to pry the bottom panel. To make your job easier, you have to start from the back.

2. Battery

Weirdly enough, the battery capacity here is only 55Wh.

3. Мemory and storage

Hidden beneath a metal plate, there are two SODIMM slots for up to 64GB of dual-channel memory in total. Additionally, you get two M.2 PCIe x4 slots for SSDs and one 2.5-inch SATA drive bay. Thankfully, Acer was thoughtful enough to include connection hardware for the 2.5-inch drive inside the box.

4. Cooling system

Cooling-wise, there are two heat pipes shared between the CPU and the GPU, one more for each of them, and one dedicated to the graphics card VRMs. In addition to that, you can see two rather large heat spreaders, taking care of the graphics memory and the VRMs for the processor. Although Acer is very aggressive in their marketing for the so-called “AeroBlade” fan technology, only one of the fans seem to make use of it.
