This modpack is based on automatization and building factories, it has building mods and factory mods. You can do a lot of things. I really like the combination of fancy building and automatization in this modpack. In this modpack you can do whatever you want. You can use Applied Energistics to store all of your diamonds, and if you are lazy you let your network craft everything for you. DO you need a lot of power? Build a Reactor with the big reactors mod. Do you want a fancy building? Check out the Chisel 2 mod. Did you thought there weren't any triangle shapes in Minecraft, they exist in this Modpack.
Mods Included that are not downloadable from Curse and don't show up in mod list are:
Big Reactors 0.4.3A -- http://www.big-reactors.com/
