The REEpack

For you, if you don't happen to own a good pc, but still want to play modded Minecraft.

The REEpack offers the ability for people who don't have powerful computers to enjoy modded Minecraft. This modpack is quite light (about 55 mods) which makes it easy to run on most pc’s.

The big decrease in amount of mods compared to most mod packs in this pack allow for smoother frame rates on lower end machines, and lower power draw on higher end machines, while trying to make the game as enjoyable entertaining as possible, even with the decrease of mods in the pack. By using the mod pack, the game becomes more immersive compared to vanilla, unmodded minecraft.

You  can build a massive storage system with Applied Energistics 2, or grow almost any material in the game with mystical agriculture, or forge custom tools with Tinker's Construct.
