Please for your own sake, don't use the setup Etho is using. Etho is still very much a newbie to all of these mods, and his setup is very inefficient. By all means, go for the same goal, but pay more attention than he does to how the mods behave. For instance, don't run Copper Cable for more than four blocks. You also should try to arrange the pipe for even distribution rather than a sloppy line. I suspect many of his cells are going to wind up scattered about and very slowly accumulating in the later ones, taking ages to build up the necessary full stack. At the very least, he should be focusing on a single centrifuge for now and slowly building his way up as he has enough tin production to handle multiple stacks.
