I found a modded Minecraft server called The Volkrune Realm.
It is mostly based around Valkyrien Skies2 with clockwork warium and superb warfare. The whole vibe is more like building moving stuff and messing with machines and combat mods.

GG.MINEWIND.NET New Server IPLifesteal SMP PVP Raiding Starts Feb 28
I found a Lifesteal SMP that is starting on February 28th. It is built around PVP and base raiding so people can fight and go after each other.
The lifesteal part is tied to PVP deaths. You only lose a heart when another player kills you so natural deaths are not as scary. They are looking for more players to join.
