Not sure who was being negative about DIY, probably because I don't read many of the threads, but isn't DIY sort of the backbone of this hobby?
I think maybe DIY bragging might be self delusional at times as people are giving advice, but DIYing your own system has tons of advantages.
You can't take away from the guys that have the experience in doing things, as probably some DIYers do but compare DIY to expensive plug & play and I would think at least it's a fair shot that the DIYer is going to make something in the end that will out do or come close to, once they learn the tricks.
