I know the topic sounds silly, but my wife bought this pre-built which includes a single stick of 16gb DDR5 RAM. I figured I'd slowly upgrade it over time and start by adding a second stick, but in my searching I've only been able to find them in 2-packs. The build came with this particular RAM. Is this even possible or am I chasing after nothing? lol

At about 10:57 in this video, Zchum flips a switch and the wooden window shutters automatically close. What did he use to create that effect? I noticed something attached to each shutter but I'm not sure what it is. Thanks!
