What use cases are you planning for it? I mean, antiX would totally rock on that machine. However having Wayland, being lightweight and easy to maintain is kinda tough to find. Lose Wayland part, it’s antiX. Lose lightweight part, it’s Pop OS, openSUSE Leap, etc. Lose easy to maintain part (for a newbie), it’s Arch (mostly derivatives that come with a GUI installer).
Though if I was preparing that device for someone else, I would probably go with LMDE.
I see. In that case I see no reason not to use antiX. It’s so lightweight it can run well on a 20 year old laptop. You don’t need latest drivers to play Minecraft (you can install them if you want like on any Debian base but there is no need for that). antiX is also easy on hard drive space since it’s smaller than most distros.
