Hardware specs

I have been a user of many PC based DJ programs, but looking to get into VJ. I am wondering what hardware is recommended. not just specs, bu a specific model that is known to work and work well. I also need to know what else I need to VJ? Is there software that can rip my DVD movie tracks into MP4 easily and quick?
Your guidance is greatly appreciated.
Thanks and keep on rockin'
