I suggest four config options:
EU Output for the fusionreactor & the lightningroot (like the config for the gens in the ic2 config)
Working speed of the industrial centrifuge
Bauxit generation amount (like the config for the iridiumore)
An extra option for the disabling of the old matter fabricator
I quartered the eu output of all the gens on my server and i want to use your massfab as an expensiv (build mats) but effective (matter/eu) matter source and the old one as an cheap but ineffective matter source.
