How do you get your initial nether quartz so fast (for the fluix)? 3 -Minecraft days- which is one RL hour of play. It would take that long to set up the portal.
What exactly is your idea of a small AE system? I'm guessing a controller and ME chest with storage and a couple of basic import/export busses (as I assume OP wants to automate, not merely store things).
How do you get it so fast?
I can get to the nether before the end of the first mc daylight hours-as long as I don't make easy transportation from surface to lvl 11. It would almost never take me past the end of the first mc nighttime.
You don't need diamond to do it. You need 3 iron, for a bucket. A 4th iron if you want flint and steel instead of doing it with burning planks.
Just gather 3 or 4 trees worth of logs.
Make a wood pick
Dig down
Make stone picks
Dig down to lvl 11 (there is a safe way to dig straight down)
At lvl 11 dig in a straight line until you hit lava.
If you haven't found iron by now, dog out your room for the portal until you do.
Make a bucket and pillar back to the surface and get a bucket of water.
Dig back down and pour a nether gate. (watch DocM and JL zipcode's team UHC to see JL's easy pour method)
Light the portal and head in.
Dog inside the nearest wall and stay under the forgave to avoid mobs.
It is fairly easy.
Kill something for food while gathering wood and you are set.
