If you want to throw some serious money at it and use some expensive hardware, that's your choice. On the other hand you can put old hardware to use instead of throwing it away, thats also your choice. I just fold with the machines available to me, at times that fit into what I'm doing at that particular moment, you guys fold whatever way suits you best. I think Stanford are greatful for the processor time whichever way they get it.
