I was wondering what it would cost to build a DS from scratch? I think i saw motherboards for like 40 bucks. screens are 22 something. and a case is about 13 or so from the infamous DX. Sow what are we up to? 40+22+13= $75 Now im not sure what i would be missing. A case comes with buttons, screws, and obviously a case. A battery 3.50, L and R pads 1.44, power button 1.30, button pads 1.22, and power switch 1.30, and speakers 1.92, wifi antenna 2.22, mic 1.63, hinge shaft 2.23... $15 more. so 90 bucks? What am i missing?
