Good post! For my first DIY case, I nearly maxed out the power with a Konstant Labs StrongPWR. It most likely provides more power than I can ever use in a 2x 84hp case. Why did I do it? Well, it comes in a nice package deal with two filtered bus boards that instantly got rid of the hiss plaguing my Intellijel 7U case when connected to my iPad. Second - is it really that expensive indeed. I think €250 or thereabouts was well spent on peace of mind.
