I'm building a new pc and I'm on a bit of a budget so i'm just reusing parts from a x51 r2. I want to know if I can reuse the motherboard because I can't afford one and I just bought a gpu, psu, case, and cpu cooler please help me. Also take a look at this video to get idea for the motherboard. https://www.youtube.com/watch?v=-RQ-IW8fIqs&feature=youtu.be&t=7m45s
