Hello linux community

I'm a somewhat long time Ubuntu Linux user who likes unity de over others, and also a gamer who, currently uses integrated graphics. my first ubuntu versions were 17.10 with gnome, and later/longer 16.04 with duelboot, eventually swapping to full linux. built my first custom pc, and was upset to know 16.04 will not install there. I wanna swap to arch if unity, or unity-like de is possible so i'll probably gonna need help with this distro hop. and not much else to say. wanna share my small Ubuntu knowledge and learn along the way.
