Based on the idea, that 100x25 grid designs are highly tileable from the equator out, I designed a late-game science complex. It creates all 5 science cubes in equal proportions, combines them with antimatter for 135-per-minute white science and has 9 matrix labs for on-the-spot research. No export needed, and everything is fully proliferated and created from base ores materials: kimberlite, organic crystals, stone, iron/copper/titanium/silicon ore, fire ice, hydrogen, raw oil, water, critical photons and proliferated strange annilihation fuel rods. It is very compact, but an unholy spaghetti mess ;-)
This complex draws <1GW (including local mining) and is currently set-up to ILS-import only critical photons, fuel rods, fire ice, hydrogen and kimberlite ore, but does not include logistic drones. Change as needed. I can be started "cold" by supplying initial warpers (if needed, they are produced by the complex as soon as green science starts trickling in), but proliferator mk3 takes a long time to be created -- as it depends on carbon nanotubes -- and to fill all belts and sprayers, so peak output of hashes from 135-per-minute white science cubes takes about 20 min.
Third screenshot shows tilability, but you need to remove the lowest row of power towers in order to "cross" tropical boundaries...
