Just a collection of mods I want to use for a server for play with my pals.
It includes popular mods like updated Tinker's, Bibliocraft, Thaumcraft, Atum, BetterFPS, Mekanism, Thermal Expansion, and many more. Hexxit Gear, Atum, Biomes O Plenty, and Twilight Forest are the crux of the exploration mods. Tech is here in the forms of Mekanism, Thermal Expansion, Tinkering, Foundation, ComputerCraft, IndustrialCraft, ProjectE, Redstone Flux, and Tinker I/O. I love Tinker's Construct, so that's in there as well as some other additives like Tool Leveling and Numina.
It is pretty lightweight, as it has under 70 mods. I recommend at least 4 GB of memory allocated to the mod. I have tested it with 3 GB, it can still run. I happened to be hosting the server on the same computer I was playing on temporarily...so don't follow in my footsteps. I'd still recommend 4 GB though.
