While my Home Assistant is running OK on my Raspberry Pi, I really want to be able to run the Visual Studio Code app and it only runs on x86 architecture. Additionally, it would be nice to have a little more power behind HA. I acquired an Intel Atom based NUC to keep the power requirements down so it's not a huge performance improvement but that combined with a SSD rather than a CF card and a bit more memory do make for some speed improvements.
