In case you didn't already know,
Mystechcraft is an anarchy minecraft server, where you are free to essentially do anything. The rules we do have are mainly to keep the server properly functioning. Griefing etc. IS allowed, because the map size is unlimited, and there are many different possible dimensions you can travel to and setup bases within.
We have recently updated to 1.7.10!
The pack is available via FTB.
